An executable packer is not a demotool...
added on the 2005-07-21 15:22:12 by zoom zoom
I don't know, its a tool created by sceners explicitly for the purpose of efficiently packing 4kb intros. It deserves to be here a lot more than some other "demotool" prods.

Personally, I'm more interested in Blueberry's unreleased Amiga packer...

On a totally unrelated note, the best-named packer in history was "Turtle Smasher". Pure genius!

nice idea to include its own linker!
rulez added on the 2005-07-21 16:14:34 by toxie toxie
just tested it and it improved my size with only 6 bytes compared to 20to4.. but it seems like it's far more stable then 20to4 atleast ;)
so long all the problem with cab dropping
rulez added on the 2005-07-21 18:50:51 by bzz bzz
and oh, i must ask, doesnt the link.exe trick work with VS 6.0 ?
added on the 2005-07-21 18:52:23 by bzz bzz
You shouldn't directly compare filesizes with 20to4 on smaller files (in boozies case ~3000b). Crinkler has an 450byte(~200bytes header) overhead to compensate for before it can gain any bytes compared to 20to4. Crinkler being able to match CAB-dropping on your 3kb file actually shows good promise that you could gain at least 100+bytes compared to 20to4 on a final 4kb file ;)

i just want to say that this packer truly rocks! i love you guys!
added on the 2005-07-22 01:47:43 by kusma kusma
a very elegant solution. neat VS integration, neat exe only output. and most importantly, great compression rate.

reflecting to the manual: avoiding dropping is elegant, but cabinet.dll is no cheating (just like opengl32.dll is no cheating either). it is even possible to use cabinet.dll and LZX without writing to the disk. this still has unexposed potential.
rulez added on the 2005-07-22 03:30:04 by Ger Ger
Gem: You are right, using standard Windows dlls is not cheating. But running an external program from a BAT file somehow leaves a bad taste in your mouth. And it doesn't work on my system at all.

Dropping is the thing we are mainly rebelling against. And the best way to do that is to make something competitive.

I doubt you would get good results from using cabinet.dll for in-memory decompression. Compression based on context modelling is sufficiently superior to LZX to make up for the extra 200 bytes of decompression code on a 4k.

Version 0.2 is now online.

This version fixes a bug in the decompressor, discovered by Frenetic, which would decompress garbage in some "rare" cases, such as when compressing Parsec in SLOW mode. :)

There are also various corrections and updates to the manual and some other minor changes.

Enjoy! :-D

my first feedback: crinkler-.exe was slightly bigger (5000 something) then using a .cab-hack (4800 something)..

good work, maybe i should stop working on 20to4 as obviously crinkler is (at least for me)
a much better solution right now :)

toxie: Interesting... Are there perhaps any big blocks of zero data in your file?

We would be delighted if you could send us a copy of your obj file that compresses better with cab, so that we can have a look at why we fare so badly.

Blueberry: I will as soon as i think i have a version that's worth it.. Also this was just a quick try (getting it to work somehow), so i bet i will squeeze some few more bytes out of the crinkler-.exe somehow..

The next release version will be Windows 2000 compatible. We have designed a new header layout for that which is actually smaller than the old one when the number of imported functions is low, as is typically the case for DirectX-based intros.

It will probably be some time before the next release, though. A couple of weeks at least, I expect.

Great! I've just tested with same params than 0.2 and i win 28 bytes, really great.

I lose about 20-30 bytes on all my prods
added on the 2005-10-31 22:14:55 by shash shash
The compression heuristics used in 0.3 are slightly different from those in 0.2. Some intros get smaller, some get bigger, especially those with many imports (since the new header has space for fewer imports).

Try enabling call transformation. It might very well save you those bytes back (depending on how many calls you have).
added on the 2005-10-31 22:35:41 by Blueberry Blueberry
Actually, all the intros that I've tested (openGL) get quite bigger with crinkler 0.3, so i'll stick with 0.2, even with call transformation.
added on the 2005-11-07 19:07:42 by shash shash
Hmm, it really shouldn't get that much bigger.

It would be great if you could send us the object files for the intros you have tried compressing. Then we can investigate what causes the blowup and maybe fix it for the next version.

rulez added on the 2005-12-18 23:45:12 by StingRay StingRay
We haven't done alot of testing of crinkler with vs2005, but it seems the link.exe drop-in trick
doesn't work directly, as vs2005 doesn't search for link.exe in the project folder before the vs /bin folder.

As a quick fix you can explicitly add the folder containing crinkler(renamed to link.exe) to
the top of your executable path in vs2005.

This is far from an elegant solution, but this is the best we have come up with so far.
We are of course open to suggestions on how to make a more smooth integration with visual studio.

Happy crunching :)

Really useful piece of code, when it comes to 4k prods. :)
rulez added on the 2006-03-13 19:17:47 by KK KK
selmi: Yes, we scrapped Windows 98 from the start, since it is not relevant for demos nowadays. Just like most other software makers, we consider Windows 98 obsolete.

Not working in WinE is a bit worse, although it doesn't come as a surprise to me. Crinkler EXE files are made for the Windows PE loader (in Windows 2000, XP and Vista), rather than the PE file format specification. The WinE PE loader probably contains a lot more sanity checks than the WIndows PE loader, which is why it rejects Crinkler-compressed files.
added on the 2006-03-19 14:00:01 by Blueberry Blueberry
Just today I measured a 4k with apack and with crinkler and crinkler saved an incredible 450 bytes (using GCC). Given you require an additional 450 for your unpacker its an amazing achievement. Great work Mentor and Blueberry. When I get a heart - you get it.

Why don't you Free the memory you use for decompressing? If freeing this Memory uses to much space you could make an option for guys who don't need this space.
added on the 2006-08-08 20:17:20 by Freak5 Freak5
The memory used for decompressing overlaps the memory for the resulting executable image itself. So if you allocate your memory statically, it will reuse the memory used for decompressing. If this is still too big, you can reduce it using the /HASHSIZE option.

It works with VS.net 2005, and you don't even need the link.exe trick.
Just add a crinkler command-line step in Project Properties / Build Events / Post-Build Event, something like this:
Crinkler.exe /CRINKLER /VERBOSE:IMPORTS /OUT:$(OutDir)\$(InputName)_crinkled.exe <libs> <objects>

Btw, does it work with Windows Vista?
rulez added on the 2006-10-10 17:07:39 by nap nap
I just installed Vista RC2 to find out, and unfortunately the answer is no. We will of course investigate this to figure out what goes wrong and fix it for the next version.
In the meantime, don't worry about your intros not running on Vista if you use Crinkler. We will provide you with some means (such as a recompression option) of making intros compressed using non-Vista-compatible versions run on Vista.
added on the 2006-10-31 22:02:35 by Blueberry Blueberry
OK, the problem turned out to be very easy to fix. Here is manual fix that you can use to make intros compressed using Crinkler 0.3 or 0.4 Vista-compatible:

Using a hex editor, change 93 into 50 at offset 6A and change 53 into 93 at offset 74. For 0.3-compressed intros, you have to additionally change cdm.dll into lz32.dll at offset 9C. Voala!

Now let's all cross our fingers and hope that Microsoft don't change anything drastic between RC2 and the final release. ;)

Crinkler 1.0 pre-announcement:

We are currently finishing the last bits of implementation for Crinkler 1.0, which will be released at tUM 2006. Major new features include:

- Windows Vista compatibility
- Greatly improved compression ratio
- Section reordering to optimize compression
- Big speed improvements
and lots of other stuff.

The new version will be available before the 4k graphics and 4k intro deadlines. Expect to win at least 100 bytes compared to 0.4.

Why does a cm-based packer like crinkler need the lempel-ziv lib lz32.dll for decompressing?

rulez added on the 2007-03-31 11:30:21 by trc_wm trc_wm
cj: We were actually joking about when someone would notice this suspicious looking import.
Crinkler uses hashed importing exclusively and as such doesn't need an import table, but the PE-loader in win2k crashes on executables without at least one import. To fix this we had to include a dummy import table importing some arbitrary function. It just so happens that lz32.dll has the perfect combination of a short name and availability on all windows version :). This also explains why this dll isn't referenced in versions of Crinkler prior to the win2k fix.

Also lz compression isn't really of much use for 4k compression today, even if it is free :D
(People gave up on cab dropping for a reason, even though it has essentially no depacking overhead)

Mentor, Blueberry, I have a small request that you probably will not like to implement, probably it doesn't fit in Crinkler's way of working but...

as you know floating point numbers compress bad, so people is using the trick of truncating the mantisa with 16 bit of zeros (collapse/necrostudios, farbraush, myself, and probably others). I'm not even sure if Crinkler has enought information to know if a specific constant in the .data segment is a float or not, but would it be possible that you automatically do the truncation for me at linking time? In other to avoid truncating every float (sometimes you don't want truncation for precision issues), only those constants starting like "ct16_" (Crinkler Truncate 16 bits) could be truncated...

I'm saying impossible things? Sorry for asking more from you... Second thumb up to compensate for it :)
rulez added on the 2007-07-02 22:20:10 by iq iq
another option I would be happy with is to do it per .cpp./obj somehow (like the .obj starting with the indicated prefix) or by function (but this I understand means some logic to inspect the binary the code at link time.
added on the 2007-07-09 23:43:56 by iq iq
Thanks for the suggestion iq. We are working on that feature now, so you will probably see it in the next release (which will be fairly soon).

A tricky part of it is to recognize float constants that are not marked using a special label. It is possible for float constants in the code, since these are put at a special label by the compiler, but other float constants do not appear to be marked in any special way.

But your suggestion of using the label or file name as indicator is good. Using that will be much easier than truncating the values manually.
added on the 2007-07-14 00:22:02 by Blueberry Blueberry
Hi. I'm currently writing direct assembly by hand. Would it be possible to have tips/information on crinkler (and it's packing algorithm and segment reordering) so I could perhaps better align the code/data. I expect my data segment to be vastly bigger than the code segment, and the data segment could be split quite freely. Website or the Manual.txt would be a good place for this information.

Thanks again for this great tool. :)
rulez added on the 2007-07-29 19:25:50 by XMunkki XMunkki
XMunkki: Yes, as mentioned in the manual, you should split your code and data into as many sections as possible (that is, only group data that is addressed from the same label). This gives Crinkler most flexibility in choosing a good section ordering.

It is also usually a good idea to give uninitialized sections a high alignment, e.g. 256 bytes or more. This makes your pointers to these sections more similar, resulting in better compression.

rulez added on the 2008-01-12 22:15:23 by Pirx Pirx
Long, long overdue, but finally, here it is: Crinkler 1.1!

Main new feature is the compression report: A detailed report on the compressed intro with colorcoding to indicate the compression ratio for every byte of code or data. On top of that, it provides disassembly of all the code with all crossreferences as links. Try it!

And then there is the float truncation feature. It is somewhat experimental, as the automatic detection of float constants is necessarily based on heuristics. We are very much interested in feedback on this feature. Is it useful as it is? Any suggestions for improvements?

On the compatibility front, the executables are now compatible with data execution prevention. And, as promised, weak externals are supported now.

The rest are minor fixes and tweaks. See the web page and the manual for the full list.

The compressor itself is unchanged in this release. The only case where the file size will change is if you do not use ranged import. A slightly smaller version of the import code will be used in this case.

@Blueberry: I've actually got it to work :D

Dev-C++ outputs the .o files (mirrors of VC++'s .obj files) automatically, so I just made all my code one file and copied VC++'s .lib files that I needed and it works just fine now.

I'm acessing the same dll's so there's no need to use gcc's .a files instead of the .lib files crinkler needs.

All in all I got it to work and it was much easier than I thought. Also, CAB dropping got 1.92kb and this got 1.5...so you are a beast, Crinkler!! :D

Lord Graga: We use several Windows-specific system calls (such as DLL loading) inside Crinkler itself, so it isn't easily ported to other platforms.

However, you could try running it with Wine. As far as I know, Crinkler works fine with Wine, and Wine is available for (x86) Solaris.

Great tool without any doubts! Always proving how lame I am at theory of information. I still get surprised by the increased packed size, while original size is decreased by 10-30 bytes of data or code (badly influencing surrounding context?). Also I sometimes get worse rates when I have more data_seg-s. More advices on dealing with this masterpiece would be highly appreciated 8)

Great tool! Question though. I was working on building a very minimal exe using VS 2008. I went the route of putting the crinkler.exe file in my $SolutionDir and renaming it. But, when I run it I keep getting the following error:
fatal error: LNK 0: could not find symbol '__imp__LoadLibraryA@4'
I am not linking against any crt and my project builds fine in Release and debug mode. I am *not* including kernel32.lib in my linker dependencides, which solves the problem. Why is this needed and is there a way I can get around it?

Hi, thumb up and, of course, I have got newbie question too. I'm using CodeBlocks w/MinGW (thus it's not VC++, because I've problems with registering VC++ 2008 Express Edition). I took aulds OGL Framework from in4k.untergrund.net and placed it in main.c.

Compiling and linking looks like this (/range, /transform-calls and other option temporary disabled, since the code currently is small)
mingw32-gcc.exe -Wall -Os -c main.c -o Release\main.obj
crinkler.exe /subsystem:windows /LIBPATH:"C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib" /out:Release\AuldOGLFramework.exe opengl32.lib gdi32.lib kernel32.lib user32.lib Release\main.obj /COMPMODE:SLOW /HASHSIZE:256 /HASHTRIES:256 /ORDERTRIES:1024 /UNSAFEIMPORT /PROGRESSGUI
This leds to 641 bytes, through aulds talks about results of around 482 bytes. Is there any switches to compiler and linker I'm missing?

and a second q, I've tried to rename main.c, to main.cpp and got the following error from crinkler:
fatal error: LNK 0: could not find symbol 'WinMainCRTStartup'
Looking into main.obj, I saw this
How to make it look like _WinMainCRTStartup@0?

Another year, another Crinkler! Version 1.1a is now available.

This release focuses on bug fixes and usability. The only change affecting compression rate is a bug fix in the interaction between call transformation and section reordering, which will probably give you a few bytes if you use both.

Apart from that, the long-known float truncation crash bug is now fixed, and there are some improvements to the HTML compression report.

On the usability front, Crinkler now try to detect if some feature is used that Crinkler does not support and gives a helpful hint, e.g. "Disable 'Basic Runtime Checks' in the compiler options". More importantly, there is a new section in the manual which describes how to go about using (or not using) the standard C runtime library with Crinkler. This will hopefully alleviate some of the problems people have had with getting Crinkler to work.

See the web page and the manual for more details on the new version.

If you have any comments, especially if you find cases the manual does not cover or which could use a helpful hint from Crinkler, please tell us. Enjoy!

when i try to use crinkler on obj created by masm here is what i get :

warning: LNK: Entry point hunk has alignment greater than 1, forcing alignment

error: LNK: Cannot find symbol '__imp__MessageBoxA@16'

the strange thing is i dont have any MessageBox call inside my asm file

C:\masm32\bin\Link.exe /STACK:0x200000,0x200000 /LIBPATH:"C:\masm32\lib" /SUBSYSTEM:WINDOWS framework.obj => works

crinkler framework.obj /SUBSYSTEM:WINDOWS /ENTRY:EntryPoint /LIBPATH:"C:\masm32\lib" /CRINKLER => error message
added on the 2009-01-23 21:58:53 by Tigrou Tigrou
Tigrou: By default the Crinkler decompressor will display an error message (using __imp__MessageBox@A16) if the executable imports from a dll file not on the users system. With the widespread use of the d3dx9_xx family of dlls this is no longer an unlikely scenario.

By using the /UNSAFEIMPORT switch you can change this error message to a simple crash and reduce the decompressor overhead slightly. This is perfectly safe, if you are only using standard dlls.

Crinkler, unlike ms link, doesn't link with any default libraries, so you will have to explicitly link those you, and Crinkler, need. Crinkler needs at least kernel32.lib, but will also need user32.lib if the /UNSAFEIMPORT flag is not used.

If you have further questions about Crinklers quirky behavior, let us know :)

rulez added on the 2009-02-08 22:48:17 by scenebas scenebas
scenebas: OK, here's a MessageBox example for NASM:
Code:extern __imp__MessageBoxA@16 global _entry section main text align=1 _entry: push byte 0 push title push body push byte 0 call [__imp__MessageBoxA@16] ret section str1 data align=1 title: db "Crinkler",0 section str2 data align=1 body: db "Read the manual!",0

Assuming you have assembled this code into an object file called mbox.obj and that the LIBPATH is set up correctly (this is the case if you are running a Visual Studio Command Prompt - otherwise you will have to manually point it to your .lib files) the command line to link it is simply
Code:crinkler mbox.obj /ENTRY:entry kernel32.lib user32.lib

This should result in an out.exe executable of 576 bytes.
Add further options at your leisure.

Does that answer your question?

The Windows 7 problem is present on RC1 as well
added on the 2009-05-07 21:15:17 by emoon emoon
Thanks for the reports about the Windows 7 problem. I have investigated it using RC1 and identified the cause of the problem: The digging-into-process-structures hack we use to retrieve the address of kernel32.dll apparently does not work on Windows 7. It gives back the address of a new Windows 7 DLL called KernelBase.dll, so when the import code thinks it is calling LoadLibrary, it is calling some bogus function in KernelBase.dll instead.

We need to investigate this some more to determine how to obtain kernel32 in a way that works on both Windows 7 and earlier Windows. Hopefully we can find a method which is the same size as the old one, since this will greatly simplify the task of fixing old intros to work on Windows 7 (not to mention keeping the size down when adding Windows 7 compatibility).

If all goes well, we will have a fix out before Windows 7 goes public. ;)

Some thoughts regarding Windows 7 and ntdll.dll issues with older software...

Is it possible to write a 'stub' dll which retrieves a correct address for each api? Such 'transparent' solution will help to run a lot of incompatible software on Vista/W7.

I love the thumbing for tools. I wonder what the rating for bass wouldve been if it was added 10 (?) years ago.

Is tools added to top10? If so, it would mean that all demomakers (ie not at all the majority of pouet users) would thumb up the proper tools and therefor removing themselves from top10.. if pouet where from/by demomakers that is.

The moral is that we never should have any censorship or let the demoscene outreach people govern this site. The majority of pouet.net is not demomakers they are just here because Iam. It's my fansite and you all have accounts to enlarge me.

See http://www.harmonysecurity.com/blog/2009/06/retrieving-kernel32s-base-address.ht ml - it's only 2 bytes larger.

Also, all programs are called from kernel32:BaseThreadInitThunk, so you can use 11 bytes to get the base:

push edx
dec edx

rrrola: The method in your link is exactly what we came up with for the new import code (except we use the InLoadOrder list). The article mentions that the method sometimes does not work on Windows 2000. We have identified the exact circumstances under which it works, which is when kernel32 is imported as the first DLL in the executable's import table (so no easy fix for shellcode here).

The second method you mention was used for the first few versions of Crinkler (up to version 0.3). It only works on 32-bit versions of Windows.

That was new to me. You really should write an article about Crinkler's headers - I doubt anyone has tested the whims of various loaders as thoroughly as you. It would make writing custom compressors a lot easier.

When linking mingw .o files against msvcrt (vc6 one), crinkler is unable to find __alloca. Which seems to be not very sane, as msvcrt should have one. Making all variables static solves this (and I believe this is the right way to make a 4k, however, i've seen quite contradictory compression results with statc/not static vars using gz-dropping on linux).
added on the 2009-07-01 05:29:21 by provod provod
w23: This might be some special issue with __alloca (it is a sort of weird thing to do anyway - it doesn't seem like the kind of thing that can be implemented by a library without any cooperation with the compiler). If you send us a "faulty" object file (preferably with source), we can have a look at it.

I agree that static allocation (using global variables) is usually the best solution for 4ks. We have often seen reductions in size when making variables global, in particular when doing it for all variables which are used in a particular way (e.g. all COM object handles).
added on the 2009-07-01 09:31:20 by Blueberry Blueberry
i think __alloca is just an alias for __chkstk (the guard page "make sure to hit every page at least once" mojo), but i'm not certain.
added on the 2009-07-01 09:51:08 by ryg ryg
ryg: That makes sense. It also explains why the call goes away when things are allocated statically. Still, if msvcrt.lib has one, Crinkler should be able to find it.
added on the 2009-07-01 10:08:27 by Blueberry Blueberry
blueberry, not if it's part of the crt startup code that's always linked statically :) lemme check...
added on the 2009-07-01 10:19:21 by ryg ryg
Code:alloca_8: ; 8 byte aligned alloca _alloca_probe_8 = alloca_8 push ecx lea ecx, [esp] + 8 ; TOS before entering this function sub ecx, eax ; New TOS and ecx, (8 - 1) ; Distance from 8 bit align (align down) add eax, ecx ; Increase allocation Size sbb ecx, ecx ; ecx = 0xFFFFFFFF if size wrapped around or eax, ecx ; cap allocation size on wraparound pop ecx ; Restore ecx jmp _chkstk

i think that's the equivalent in current versions of the CRT. so, yeah, __chsktk wrapper taking 8-byte alignment into account.

For some reason, whatever I try, I can't get crinkler to work on any other COMPMODE than INSTANT. Everything else crashes crinkler when compression should begin. I'm running Windows XP x64 SP2 and using VC++ 2008 Express.

Even with INSTANT I get amazing results, but it'd be awesome to see what the difference would be with say SLOW for instance.

We got a message while using crinkler v1.2 in VS2005; compilation fails with the following message :
"|-- Estimating models for code ----------------------------|
Project : error PRJ0002 : Error result 3 returned from 'E:\tits-910d\link.exe'."
Getting back on v1.1 resolved the issue.

Thanks for all the crash reports. So far we have been unable to reproduce the problem on our own machines (with similar OSes to the ones mentioned in the crash reports), so our strategy will be to try to get access to a crashing machine to test on.

Anyone who wants to contribute towards this goal can do so by bringing a crashing machine to TRSAC 2009, where we will be present and ready to do the debugging.

This sounds so scary that I wonder how the heck you can gain bytes from an already optimized-to-death code.
added on the 2009-10-23 19:06:47 by decipher decipher
I've tried producing some extremely low entropy code (99% of it are mov/push/call, all using just eax register), and I have just one question from my side: is there any way of removing import-by-hash code in favor of native system imports (there is not much functions in D3D code anyway) or moving import code to the end of the code section (which would mean one extra jmp, but entropy gains may be worth it)? Maybe I'm totally wrong about it, but I think import code sitting in front of intro code may sometimes setup prediction tables for different coding style, than rest of the intro uses.

Decipher: Certainly rrrola has different definition of optimized-to-death (maybe we should call it optimizing-to-afterlife). ;)

Is possible to decompress everything from EXE file?
rulez added on the 2010-06-05 19:15:21 by cx cx
There currently exists no decompressor for Crinkler-compressed files. The closest thing is the /RECOMPRESS option of Crinkler 1.2, which produces a new Crinkler-compressed EXE. If you just want to have a look at the code and data in the file, you can combine /RECOMPRESS with /REPORT to get a disassembly and hexdump of the contents of the EXE.
added on the 2010-06-27 13:24:41 by Blueberry Blueberry
After i recompiled my 4k with VS2010 and crinkler i notice the exe is much bigger. I check it again with VS2008 and the exe was smaler. Without using crinkler in both VS Studios the exe file was same size. I quick my both report files but i dont have to much time now to find out.
can someone confirm this ????
added on the 2010-08-18 17:38:01 by Ciclope Ciclope
Ciclope: the uncompressed file sizes are probably the same because they are aligned to 512 bytes size.
added on the 2010-08-18 17:52:07 by Gargaj Gargaj
Just make sure no extra bullshit such as the path the the PDB is embedded within the executable. You have to know your compiler as if it's your partner's body. :)
added on the 2010-08-18 18:14:41 by decipher decipher
@ Decipher

I have in both VS the same compiler and linker settings. And of course is the same Code. Now i will look the ASM report file from crinkler to find out.

Gargaj: Yes i know what you mean, but i mean the real exe size not the aligned size saved on HD.

merry: Crinkler removes any function which is not called from live code, if the compiler has placed the function in its own section (Crinkler can only remove whole sections). Check the compression report to make sure the function is gone.
added on the 2010-10-17 13:51:29 by Blueberry Blueberry
About the crash problem: We are almost certain the problem is with the OpenMP implementation in the Intel compiler. We are investigating alternatives.

One option is to use the Microsoft compiler instead. However, the OpenMP implementation in the Microsoft compiler does not have an option to link statically, which would necessitate an OpenMP DLL alongside Crinkler. Besides being cumbersome (you have to remember the DLL every time you copy Crinkler around), such side-by-side deployment potentially requires some nasty manifest trickery and also violates the distribution license for the MSVC runtime DLLs (they must be installed by an installer).

Does anyone know of any appropriately licensed static library giving equivalent functionality to OpenMP?
added on the 2010-10-17 21:42:32 by Blueberry Blueberry
We found a usable workaround for AMD systems, until the problem is fixed:
Use the old crinkler 1.1 (which can compress but generates exes that crashes on windows 7) as linker, and then make a post build event that uses crinkler 1.2 /recompress to get the final exe without doing any further compression. That's only 1-2 seconds additional build time for your crinkler builds.

Crinkler 1.3 is released!

The long discussed AMD crash bug is now fixed. All that was needed to fix it was to use a newer version of the Intel compiler.

Other highlights include:
- Optimizations to the decompression code reducing the size of the header by 21 bytes. Big thanks to Řrřola for his suggestions leading to these reductions.
- New option - /OVERRIDEALIGNMENTS - to specify label alignments, enabling much higher alignments than what is possible using the normal object file alignment mechanism.
- No limit on the number of calls that can be transformed by call transform (previous limit was 255).
- Various other fixes - see the manual or the web site for the full list.

Hi everyone,

I'm trying to use crlinker tonight for the first time with visual studio 2010 express (simply hello world). I placed crlinker to my project folder and renamed to link.exe. I have strictly followed the installation part in manual.txt. But ... the linking step failed with the error code -1073740777. Is this kind of error was arrived to one of you?

"/CRLINKER" ? should be "/CRINKLER" for starters.

Another thing to be sure of is, make sure it's in your solution directory, not the project directory (though they might be the same). Look for the .sln file.

I get this error whenever I use any of the std componentes: LNK: Cannot find symbol '___security_cookie'

If I use exit(0) I get this error: LNK: Cannot find symbol '__imp__exit'

To get rid of the ___security_cookie dependency, set Buffer Security Check to No in the Code Generation options.

Use ExitProcess(0) instead of exit(0) to call directly into kernel32.dll and thus avoid this standard library dependency.

Read the section on Standard Runtime Libraries in the manual for further tips.

I tried some DX11 code, and I can get rid of the ___security_cookie error by setting Configuration Properties -> C/C++ -> Code Generation -> Buffer Security Check to No. Works in both VS 2008 and 2010 here.

I just got the following message from crinkler 1.3:


error: LNK: Cannot find symbol '__chkstk'.
* HINT: Avoid declaring large arrays or structs inside functions. Use global variables instead.

I'm not having large arrays or structs inside my function, but it's recursive, which ends up being the same: MSVC thinks you're using (its definition of) lots of stack and ends up generating __chkstk calls.

You can work around this by supplying the /Gs option with a sufficiently large value, such as /Gs999999 (http://support.microsoft.com/kb/100775/en-us).

Perhaps you might want to mention that in crinkler's hint message too.

I had a quick look at this today, and I see some things in the import code:

64678B4730 mov eax,fs:[bx+30]
could be
6467A13000 mov eax,fs:[30]
(maybe a zero in the instruction helps somehow)

mov ebx,<image base>
could be
mov ebx,[eax+08]
if placed after the fs: line, for a 2 bytes saving.

also, the check for DLL loading:
test ebp,ebp
jne OUT
push 00000000
push 00000000
push edx
push 00000000
could be
test ebp,ebp
jne OUT
push ebp
push ebp
push edx
push ebp
since ebp is known to be zero at that point, for a 3 bytes saving.

the code in the header could be shortened by at least 3 bytes, but I didn't see any advantage because it seems that nothing can move into the gap.
rulez added on the 2012-07-18 23:44:40 by qkumba qkumba
even better: ebx=fs:[30] on process start (it's even documented somewhere), so push ebx in the header, pop eax in the second stage, no need for the fs: line at all.
added on the 2012-07-19 00:02:39 by qkumba qkumba
mov eax,[edx+1C]
add eax,ebp
mov eax,[eax+4*ecx]
mov [esp+1C],eax

if ebp and edx were exchanged, you could use

add edx,[ebp+1C]
mov eax,[edx+4*ecx]
mov [esp+1C],eax

for a 2 bytes saving

extending that:

mov eax,[edx+4*ecx]
mov [esp+1C],eax

could be

pop eax
push [edx+4*ecx]

for a 3 bytes saving.
of course, the actual savings after compressing these might be 0 or worse. :-/
added on the 2012-07-19 03:13:44 by qkumba qkumba
the original PEB_LDR_DATA code could be used, if you resolved LoadLibraryExA instead of LoadLibraryA. the ExA version exists in kernelbase.dll and kernel32.dll, and it takes two additional parameters which would both be zero.

for the import table on Win2k, the requirement was to import from either kernel32.dll, or something that imports from kernel32.dll, so that kernel32.dll is loaded somehow. lz32.dll could have been wmi.dll for a 1 byte saving.
added on the 2012-07-19 05:20:40 by qkumba qkumba
Thanks for all the input.

It seems you are right about ebx=[fs:30] on startup. A quick test suggests that we can
save about 3 bytes. It does complicate the call transform code, but I think it will still be a net win in that case.
Can we rely on this across all windows versions?
It would be much appreciated if you can find the documentation you are mentioning :)


mov ebx,<image base>
could be
mov ebx,[eax+08]
if placed after the fs: line, for a 2 bytes saving.

This seems to be slightly worse, at least for my example project, because we go from 2 to 3 non-zero bytes.
Optimizing for compressed size is tricky.
We reuse the same instruction sequences, addressing modes and registers as much as possible.
In the end it tends to compress better than the more compact alternatives we have tried. (lodsd+xchg+SIB)
This is of course highly context dependent, so you would ideally want the import code and
intro code to be written in a similar style.


also, the check for DLL loading:
test ebp,ebp
jne OUT
push 00000000
push 00000000
push edx
push 00000000
could be
test ebp,ebp
jne OUT
push ebp
push ebp
push edx
push ebp
since ebp is known to be zero at that point, for a 3 bytes saving.

You do realize that these pushes are in your code, right?
Yes, ebp is guaranteed to be zero after the import code, but you will have to exploit it
yourself. We are not going to rewrite user code :)


the code in the header could be shortened by at least 3 bytes, but I didn't see any advantage because it seems that nothing can move into the gap.

Yes, gaining a lone byte somewhere in the header doesn't really help.
I'm guessing part of the saving you are mentioning is in the code around the stack reserve field.
You also need to be aware that the code inside the header is not as naive as it might seem, as it is under some additional constraints.

mov ebx, dword 3
is actually just a shorter way of jumping across the subsystem field (dword 2/3), while at the same time initializing ebx to something >1.
The next 4 fields are the reserve/commit fields for the stack and heap. We have to be extra careful about these, as they need to be small
valued dwords in order for windows not to explode, so the instructions are chosen to always have 00/01 in the most significant bytes of these 4 dwords :)


mov eax,[edx+1C]
add eax,ebp
mov eax,[eax+4*ecx]
mov [esp+1C],eax

if ebp and edx were exchanged, you could use

add edx,[ebp+1C]
mov eax,[edx+4*ecx]
mov [esp+1C],eax

for a 2 bytes saving

I tried this and it seems to be more than a byte worse than the original code.
mov eax, [edx+xxh]
add eax, ebp
This is actually one of these repeated patterns I mentioned earlier. This is the third instance of the pattern and the fourth instance of add eax, ebp , so at this point it is at a significant discount :)
I also prefer to use ebp instead of edx as it is preserved across calls, so it is easier to exploit it being 0 in your intro.


mov eax,[edx+4*ecx]
mov [esp+1C],eax

could be

pop eax
push [edx+4*ecx]

for a 3 bytes saving.

Wouldn't this store the value into EDI instead of EAX?


for the import table on Win2k, the requirement was to import from either kernel32.dll, or something that imports from kernel32.dll, so that kernel32.dll is loaded somehow. lz32.dll could have been wmi.dll for a 1 byte saving.

This is from the old header. We no longer support win2k. Also, you wouldn't really save 1 byte as it was in a 8 byte slot in the header.


the original PEB_LDR_DATA code could be used, if you resolved LoadLibraryExA instead of LoadLibraryA. the ExA version exists in kernelbase.dll and kernel32.dll, and it takes two additional parameters which would both be zero.

This sounds very interesting. I'm not really sure I follow. How do you get to kernelbase.dll and can you do this reliably on all windows versions?
Using kernelbase would result in an overhead when the intro imports from kernel32, but I guess we could redirect the imports to kernelbase in the
instances where we can. Either way, I'm curious about this :)

I'm guessing part of the saving you are mentioning is in the code around the stack reserve field.
You also need to be aware that the code inside the header is not as naive as it might seem, as it is under some additional constraints.

I understand that. I have some experience in crushing PE headers (see pferrie.host22.com). ;-)

Speaking of which, you don't need any section table at all. It is legal to set NumberOfSections to 0 since you import nothing (import table must be in a section since WinXP), and you still allocate all the memory that you want. DEP is not a problem if section alignment < 4096. I'm sure that complicates things for you, but just in case you didn't know.

mov ebx, dword 3
is actually just a shorter way of jumping across the subsystem field (dword 2/3), while at the same time initializing ebx to something >1.

Yes, but as noted above, it's already non-zero.


for the import table on Win2k, the requirement was to import from either kernel32.dll, or something that imports from kernel32.dll, so that kernel32.dll is loaded somehow. lz32.dll could have been wmi.dll for a 1 byte saving.

This is from the old header. We no longer support win2k. Also, you wouldn't really save 1 byte as it was in a 8 byte slot in the header.

If you moved lfanew to 0x10, for example, then it would fit at offset 2, with room for an instruction or two.

the original PEB_LDR_DATA code could be used, if you resolved LoadLibraryExA instead of LoadLibraryA. the ExA version exists in kernelbase.dll and kernel32.dll, and it takes two additional parameters which would both be zero.

This sounds very interesting. I'm not really sure I follow. How do you get to kernelbase.dll and can you do this reliably on all windows versions?
Using kernelbase would result in an overhead when the intro imports from kernel32, but I guess we could redirect the imports to kernelbase in the
instances where we can. Either way, I'm curious about this :)

When run on Win7, the old PEB code would fetch kernelbase.dll instead of kernel32.dll, and then call the wrong API because the hash loop exited.
So, if you resolved LoadLibraryExA instead of LoadLibraryA, then you'd get a valid address no matter which platform was used.
I haven't seen any demos using kernel32.dll, but I suppose that if one did, then you'd still have a regular import entry for it, so the behaviour would not change visibly. I will test that.

You do realize that these pushes are in your code, right?

I just checked again. It is Crinker code. It's the exit code when a DLL can't be loaded.
The "OUT" label that I referenced was the truncated process name (OUT:some address).
added on the 2012-07-19 17:14:45 by qkumba qkumba
ah ok, I misunderstood your suggestion then as ebp is also zero at the end of the normal execution. I'm running with /UNSAFEIMPORT here, so I didn't think of the error message path. Yes, that push 0 can be turned into push ebp. The difference tends to be around +-1byte depending on the style of the intro code. We are using 0 right now, as we have an expectation that sequences of
push 0 is more common than sequences of push ebp in intro code. But looking at it again now it seems to be pretty even with the ebp variant, so we should probably make it a majority vote based on our test suite of intros.

It is very common for 4ks to call ExitProcess, but that wouldn't really be a problem, as I can see it is also in kernelbase.

I tried the old import code again and it is just around one byte smaller after compression. Which will then unfortunately be negated by the need to push two zeroes on the stack before LoadLibraryExA.

Thanks again, It's great to have someone with in-depth knowledge of the darker corners of win32 look into this :)

the LoadLibrary pushes might be achieved in the header for no cost at all...
added on the 2012-07-19 20:42:59 by qkumba qkumba
that would require more than just two pushes as loadlibrary is called in a loop. we actually need two pushes per dll. this can of course still be done, but it will be at least at couple of instructions and won't be easy to fit into the current header layout and we are still talking about a potential 1 byte improvement :)

I'm curious now. If we are guaranteed that ebx=[fs:30] on all windows versions, do we have similar guarantees about any of the other registers, flags, etc.?
I get ecx=esi=edi=0 and edx=eip, but can I rely on any of this? I have tried, and failed, to find this information many times.
added on the 2012-07-19 21:23:42 by mentor mentor
okay, so forget the LoadLibrary thing. :-)

the dec al/inc al part - these seem less likely to appear than dec eax/inc eax.
would it be better to xor eax,eax before the lodsb, and then dec eax and inc eax instead?
the xor/lodsb sequence appears earlier, so maybe that helps compression.

and in that case, perhaps instead of dec/jns, you could use test/jne, and instead of the inc/je, you could use cmp eax,ebp. it's bigger, but might compress better.
you've reached the end of the list when ebp is zero.

as far as initial registers, only ebx is defined. edx=eip only if syscall mode is used (which can be disabled in some ways), other register values have changed over time.

I too have many crash with win7 fixed intros (crinkler 1.2 and 1.3). Only one seem to work well after recompress : Lunaquatic.

The issue seems to be an incompatibility with the Geforce R304 driver (from 304.48 to 306.97). The 301.42 is the last one who can properly run crinkler compressed intros.

Any fix planned?

Question about the Crinkler license...

It says "You may use Crinkler for any non-commercial purpose". May Crinkler be used for commercial purposes as well? If so, any restrictions besides "must not be used for any safety critical purpose"?

Specifically, I have a tiny two-option config utility. I've got to fit it into 4KB somehow.

question about crinkler, can I use crinkler to compile Chevrolet

No, Crinkler does not support compressed sizes of more than 64k, because of the way things are laid out in memory. Try kkrunchy (if size matters) or UPX (if decompression speed matters) for things in that size category.
added on the 2012-11-30 09:17:26 by Blueberry Blueberry
May Crinkler be used for commercial purposes as well?

No, Crinkler may not be used for commercial purposes. That could indeed be spelled out more clearly in the license.

Try leaving out the manifest, linking with the VS6 version of msvcrt.lib (see the Crinkler manual for some guidelines on this) and stripping the executable. This can usually bring the overhead down to 1k (512 bytes header + 512 bytes import table), which means you will have 3k for your code, which should be plenty for what you describe.

That is a pity. Is there no commercially licensable version, then, if not the standard one?
added on the 2012-11-30 22:39:14 by JamesB JamesB
Basically, Crinkler is an experimental hack, and executables produced by it will likely break on some future Windows version and/or graphics driver (until recompressed using a then-updated version of Crinkler). That is why we consider it unsuitable for commercial uses.

Furthermore, we don't expect any commercial uses of cramming as much as excruciatingly possible into 4 kilobytes, though we may of course yet be surprised in this regard.

It still sounds to me like the utility you are making can be comfortably squeezed into 4k by using standard exe size reducing tricks, most of which you would need to do anyway to make Crinkler happy. A few more tricks for the list:

- Define your own entry point (/ENTRY option to the VS linker).
- Define your own MS-DOS stub (/STUB option to the VS linker). Give it the first 64 bytes of any exe file as the stub file to produce an empty stub. This should make the whole header fit in 512 bytes with up to 3 sections (code, rdata (also containing import table) and bss).
- Do not include reloc information (/FIXED option to the VS linker).
added on the 2012-12-03 22:01:22 by Blueberry Blueberry
It has been far too long, but now the wait is over. Another major release of Crinkler has seen the light of day. Crinkler 1.4 is out!

Major new features include:

- The crash problem seen with recent NVIDIA drivers is fixed. Thanks to qkumba for pointing to the source of the problem: the export table pointer. This is now zero, and all is well.

- Completely redesigned header, using zero sections, a smaller PE header offset and cramming every last bit of unused space in the header (and a fair portion of the used space as well) with code. The result is a size reduction of typically 30-50 bytes for your intro. Again thanks to qkumba for guidance concerning this header layout.

- Forwarded RVA imports are now supported. This for instance enables Crinkler to link with uFMOD or libv2 out of the box.

- Dynamic C++ initializers (initializers for global variables) are supported. Direct calls to all initializer functions are inserted before the entry point. They can be disabled using the /NOINITIALIZERS switch.

- Support for setting the Large Address Aware flag on the output executable. This enables the program to allocate more than 2GB of memory (usually around 3.5GB on 64-bit systems). It is still still not possible to allocate more than 2GB statically, as this is the maximum virtual size of 32-bit Windows executables.

- Crinkler reports all unresolved symbols, rather than stopping after the first one, and indicates the object file referencing each symbol.

See the manual and the website for the full list.

Go pick it up at crinkler.net today! Enjoy! :-D

Actually, it doesn't hang, it just takes very long to get started because of the large amount of code. Given enough time, Crinkler 1.3 runs out of memory and crashes. :-/

added on the 2013-01-21 09:53:23 by Blueberry Blueberry
Hey! I had the idea of trying to gain a few bytes by putting every function in its own text section, and to let crinkler rearrange my code for optimal order for compression.

When I tried this out, I got a size increase overall due to 4-byte section alignment, and NOPs being inserted as padding.

I tried just putting one function in a separate section and let crinkler re-arrange it and gained 5 bytes, and then 2 additional bytes when I re-arranged the code manually (and let everything still be in one text section), so there may be potential.

So, the idea is to remove padding NOPs (0x90) from text sections. I have no idea if this would be easy to implement for you though (the HTML report showing disassembled code is promising, at least).

I guess you could theoretically do the same with data sections, but there may not be any way to detect this. Or well, I haven't checked, perhaps data sections are padded with 0x00?

An alternative idea, which wouldn't require the programmer to manually put stuff into separate sections, is to split code sections after jmp and ret instructions prior to reordering in crinkler. This would require an extensive rewrite of all addresses in the code though.

And hmm, I just realized that this may require relative addresses to be modified to be absolute.... this is becoming complex :)
added on the 2013-02-05 23:18:25 by cmr cmr
Forcing the alignments of code sections to 1 is actually already on our to-do list, it just didn't make it to the 1.4 release. :)

We have discussed the possibility of chopping up sections based on some kind of code control flow analysis. It would be an experimental feature at best. And even if it would work, I don't think the benefit would be particularly great. If you really need your code split up, you can do so by hand.
added on the 2013-02-15 23:52:36 by Blueberry Blueberry
Alright, if I get some time for it I'll try more manual rearrangement and see how much more I can gain in my case.

Hey Mentor and/or Blueberry,

I'm trying to make a 4K in VS2012 Express with the XP-compatible linker flag (platform toolset = Visual Studio 2012 - Windows XP (v110_xp), instead of the default Visual Studio 2012 (v110) ), and crinkler 1.4 does not like that:

To sum up the conversations I had with Seven about this XP compatibility issue:
The fix is to not select the XP compatibility option. Executables created using Crinkler will be XP compatible without it. We will make Crinkler more tolerant to the syntax of this option in a future version.

How to use crinkler in Dev-C++ with TDM-GCC x64 ? Pleaaaase
sandeeeeeh: Crinkler is a 32-bit linker. Compile your code for 32 bits and you should be fine. If you really need 64-bit code, you are out of luck, unfortunately.

You will probably need to link with some MinGW-specific runtime library. To minimize the amount of code pulled in from the runtime library, be sure to define your own entry point (using the /ENTRY option).

Let us know if you still encounter problems.

hjohn: Your code section is quite huge. Crinkler is probably running out of memory.

Does your code section contain one or more big blocks of zeros? If so, try to separate those out into a bss section.

If you actually have 200kb of ordinary code, it will probably not compress down to anywhere near 4kb, and so Crinkler is maybe not the right tool for the job.

If your code is generated and highly redundant, and you expect it to compress down to a few kb, try to generate it at runtime instead.

Hmm, i just migrated an intro from v1.2 to v1.4.
v1.3 brought "Header size reduced by 21 bytes."
v1.4 brought "New zero-section header layout saving around 30-50 bytes."
So i should get an about 50-70bytes smaller .exe in the end, right?
Too bad, i got an .exe 25 bytes bigger. Exceeding the 4096b this way.
Any Idea why this could happen? Will have a look into the manual again now, if i find a clue or a fix i´ll report back here asap.
You probably have some C++ initializers that weren't being run before. Try /NOINITIALIZERS.

Any way to save decompressed file, please?
rulez added on the 2014-09-07 18:31:35 by Manwe Manwe
Short answer: There is no such thing as a decompressed file, as there was no uncompressed file produced to begin with.

Long answer: It should be theoretically possible to produce an uncompressed executable from a compressed one. The process would include at least these steps (on top of the actual decompression, which is already there):
- parse up the import data
- find the imported functions in the imported DLLs based on the function hashes
- generate an ordinary import table importing these functions
- split up the code/data/bss section into an initialized and uninitialized part (to avoid producing a file of several hundred megabytes)
- locate the entry point right after the Crinkler import code (and call transformation code, if present)
- produce an ordinary PE header binding all these things together

We don't have any immediate plans to implement this, but we will certainly consider it if there is a good use case for it. What do you need it for?

rulez added on the 2015-04-26 17:06:42 by BoyC BoyC
las: The Export RVA is currently zero (specifically to prevent the graphics driver from crashing when it goes looking for this export), and it is not used by the decompression code (in contrast with some other "meaningful" header fields).

So yes, it should be quite possible to add an export table to a Crinkler executable. It can even be easily added to an existing executable, or during a recompression, so you can look at the size of your intro and then decide to add it if there is space enough.

The overhead will probably be around 50-60 bytes plus the lengths of the exported names. But as you say, this is probably something you could often spare in an 8k.

The big question is of course whether whoever wants to read the export table can understand the contorted zero-section layout of a Crinkler executable. But my guess is that the graphics drivers merely let the normal loader do its job and then go and look in the loaded image. So that should work fine.
added on the 2015-04-27 09:44:47 by Blueberry Blueberry
[x] Definitely interested - but no time to try it manually.

Adding it afterwards would be the best option IMHO, maybe a little tool could just do that to crinkled binaries (with options like +AMD +NV so you don't need to add the AMD string, just in case you already know that you screwed up compatibility with AMD cards).

Would allow you to first do some really expensive compression stuff and decide then, as you proposed.
added on the 2015-04-29 14:45:49 by las las
And btw. do you intend to add some more compression options for 8k?
Maybe it's possible to have a slightly larger decompressor stub in favor of (even) better compression? That would be something!

Happy anniversary to all Crinkler users!

Ten years ago today, the very first version of Crinkler was released.

We are celebrating this milestone by preparing a major new release. It is not quite ready yet, but we hope to have it out before the end of the week.

As a teaser, here are some feature highlights:

- New header and import code specialized for 1k intros, based on the 1k packer used in several TBC and Loonies 1k intros, but improved and generalized. Typically wins more than 100 bytes on a 1k compared to usual Crinkler compression.
- Ability to export symbols, as suggested by las. This can be used to automatically enable the high-performance GPU on multi-GPU laptops.
- Option to clamp context counters to better compress large, repetitive regions. Usually not a win for 4k, but useful for 8k (suggested by Seven).
- Define a fallback DLL in case a DLL fails to load. For instance, use d3dcompiler_47 if available, otherwise use d3dcompiler_43.

Spread the word to all 1k coders! Assembly is approaching, and we hope the new features will help raise the quality of the 1k compo yet another notch.

Would really love to test the Optimus stuff (I know the optimus driver does the right thing on my notebook and I can trivially check whether it works or not).

Getting there. Aiming for a release tonight.

We have the Optimus testing covered, but a test on the corresponding AMD setup would be nice. Anyone here with an AMD dual-GPU laptop?

Fashionably late... :)

Now a combined 4k and 1k cruncher, Crinkler 2.0 is born!

- New decompression header for 1k intros: smaller, but with a slightly worse compression ratio. The decompressor in this one has quadratic execution time, so don't use it for large (i.e. 4k) intros unless you want to spend minutes on decrunching. Activate with /TINYHEADER.
- New import code for 1k intros: imports all functions from used DLLs into a small hash table and finds a suitable hash function that avoids unwanted collisions. Smaller, but potentially somewhat less robust to future additions of functions to affected DLLs. Activate with /TINYIMPORT.
- Export symbols, either existing symbols or automatically created 32-bit integers, using the /EXPORT option. Can also be used with recompression to add exports to existing intros.
- Do you have big areas of very redundant data? Then the /SATURATE option might be for you.
- Use the /FALLBACKDLL option to define a fallback DLL in case a DLL fails to load. Can be used together with /REPLACEDLL to try a different version first than the one your SDK links to by default.
- Set the alignments of all code sections to 1 using the /UNALIGNCODE option.
- You can now replace DLLs during recompression using the /REPLACEDLL option, provided the DLL names have the same length.
- Header size reduced by 2 bytes. Optimization spotted by qkumba.
- Print previous size of output file for easy comparison.
- Accept values like /SUBSYSTEM:WINDOWS,5.01 which arise from selecting XP compatibility mode in VS.
- Switched from the Intel compiler and OpenMP to the VS 2013 compiler and the MS concurrency API. This is mostly for our own convenience, but also results in a smaller crinkler.exe. The speed seems to be about the same. Unfortunately, this seems to have broken WinE compatibility. Anyone depending on running Crinkler through WinE?

Furthermore, we have internally introduced a new, collision-free hashing method for model estimation and reordering. This gives consistent sizes between model estimation and reordering (the size could jump in weird ways before). It also results in slightly better compression on average, but with large variations, mainly due to the instability of the pseudo-random section reordering. Thus, some intros might turn out slightly bigger than before out of the box. Some tweaking of the contents should be sufficient to bring it below the old size on most cases. We have some ideas for a more robust way to do reordering, but due to the urgency of getting this release out, we are postponing this feature to a later version.

And NOW go and make your 1k! :-D

After all these years, this release has reminded me just how much there is left for us to do.
I hope to see some 1k intros at assembly putting these ~100bytes to good use :)

what about MASM ? Does Crinkler accept .objs ?
added on the 2015-07-28 05:01:40 by g0blinish g0blinish
I am actually sitting here somewhat in shock. I recompressed my 1k intro Molten Core and the size went down to 897 bytes...

I thought I would never bother with 1k again since there was no more room to do anything else but now I have enough bytes to maybe do something more interesting.

If I could thumbup again I would.
added on the 2015-07-28 05:05:57 by drift drift
Goblinish yes. Many 1k windows intros are using asm and crinkler together. I personally used MASM in VS2013 and it worked with crinkler just as seamlessly as coding in C/C++.

goblinish: when you download my 1k it has the source code in it and I also included a complete VS project. It should work on any VS from 2013 or newer which you can download a free version from microsoft. You can see how I set it all up but there is no real tricks, just code asm right in the VS text editor and build it just like any normal C/C++ code. If you have more questions just ask in the 1k code thread on pouet bbs, myself or many other people will be happy to help.

sensenstahl: thankyou!
added on the 2015-07-28 06:39:25 by drift drift
g0blinish: Crinkler is not specific to any language, compiler or assembler. As long as it can generate a COFF obj it should work just fine with Crinkler.

Also, this might be a good time to remind everybody that you can still support the Crinkler project by donating intro objs to us for use in our internal test suite. In particular, we seem to be very low on 1k intros :)
added on the 2015-07-28 07:31:05 by mentor mentor
@mentor: anyway is better to instal Masm32 and use one than VS2013.
some people said they are used Masm32.

@drift: thanks for the help, will try.

g0blinish: I'm not sure if you are implying that you need Visual Studio for Crinkler. The Visual Studio integration is just a convenience feature. You can also just use Crinkler as a command-line tool.

Thanks for fueling my love/hate for your work!

100+ bytes gain at 1kb is HUGE and I already fell that native 1kb intros had something like a ~1-150bytes edge other web 1kb intros, not to mention the difference of APIs and data ready to use.

Hi nebulus,

First of all, eliminate all uses of the C++ standard library and all uses of exceptions. Disable exceptions in the settings as well.

Then, if you cannot do without some C standard library functions (and thus cannot avoid a standard runtime library), try to link against the msvcrt.lib from VS6. Read the section on standard runtime libraries in the manual for inspiration.
added on the 2015-07-28 19:39:18 by Blueberry Blueberry
Is it working with MSDOS 4K ? Could it be possible ?

For MSDOS 4ks you would probably want to use a COM file, since these files have no executable header overhead.

Thus, all of the header and import trickery that Crinkler does will not be relevant for MSDOS. A somewhat similar compression algorithm might be useful, but you would probably want it to be 16 bit code and also use much less memory.

Last time I looked, aPACK was one of the most popular packers for MSDOS.

get rid of your DirectX-Template! Code something on your own by following DirectX-Tutorials to be found everywhere across the web...try to find sth official! ;) (just dont kill everything on exit as Tutorials imply, Windows will do so anyway for you!)
timeGetTime -> i got rid of it by using 4klang-softSynthesizer and using its "time", even providing you a possibility to sync music with your effects! There are other ways to avoid using it for sure, tho! ;)
The rest of your Errors seem to be soluted by just avoiding the standard-runtime aswell. (not too sure about this, because of i have no idea what this DirectX-Template is you´re using!)

Another problem you might run into is not being able to use "math.h"...
...first of all: try to avoid as much C-code as possible as it won´t pack away as good as your shader-code in Ascii! (have a large array of Ascii-Shader-Code to be compiled at runtime into shadercode, directX has a runtime-shadercompiler, use it!)
...secondary: if you cannot avoid using some math in your C-code, use the CPU directly via Assembler-Intrinsics, the only Assembler-Code you´ll ever need, except you want to squeeze out some more very few bytes lateron (never went that far myself!):
Code: //___sInUs___ #pragma code_seg(".crtemuf") float ASMsinf(float i) { __asm fld i __asm fsin } //___cOsInUs___ #pragma code_seg(".crtemuf") float ASMcosf (float i) { __asm fld i __asm fcos } //___rOUnd_flOAt_tO_IntEgEr___ #pragma code_seg(".crtemuf") int ASMlrintf (float flt) { int reti; __asm { fld flt fistp reti // rounds ;) } return reti; } //___sqUArE_rOOt___ #pragma code_seg(".crtemuf") float ASMsqrtf(float i) { __asm fld i __asm fsqrt } //___mOdUlO_flOAt___ #pragma code_seg(".crtemuf") float ASMfmodf(float i, float j) { __asm fld j __asm fld i __asm fprem __asm fxch __asm fstp i } //___AbsOlUtE_flOAt___ #pragma code_seg(".crtemuf") floa t ASMfabsf(float i) { __asm fld i __asm fabs } //___clEAr_mEmOry___ #pragma code_seg(".crtemui") void ASM ZeroMemory(void* dest, SIZE_T s) { __asm mov edi, dest __asm xor eax, eax __asm mov ecx, s __asm rep stosb } //___cOpy_mEmOry___ #pragma code_seg(".crtemui") void ASM CopyMemory(void* dest, void* souAe, SIZE_T s) { __asm mov esi, souAe __asm mov edi, dest __asm mov ecx, s __asm rep movsb } //___rAndOm_nUmbEr_gEnErAtOr___ #pragma data_seg(".rand") DWORD RandSeed; #pragma code_seg(".crtemui") unsigned long random() { RandSeed = (RandSeed * 196314165) + 907633515; return RandSeed; }

Sorry, Pouet still seems to mess up(->not recognize!) TABULATORS when pasting Code! :/
pouet seems to have added some whitespace aswell:
Just remove the Whitespace after "ASM" ;)
on top of your main-class, NOT the main()-function:

Code: #define WIN32_LEAN_AND_MEAN #define WIN32_EXTRA_LEAN #pragma code_seg(".fltused") extern "C" { int _fltused = 1; }

may help aswell!

You may have recognized those "#pragma"s everywhere, crinkler.manual has info for what those are! More than just useful for debugging, also helps crinkler itself to recognize how to handle data/code and crunch it for you! ;) Use it everywhere, as often as you want, even repeat names for them, if you think you have sth that could be the same sort of data/code...experimenting is one thing you can try if you run out of ideas getting it smaller, just some few bytes away from the final bytesize...but try planning without having to do so once you got a hang to it! ;)
Another problem you might run into is not being able to use "math.h"...

You can actually get most of this without resorting to inline assembly, simply by enabling intrinsic functions in the VS compiler settings.

I was depending on crinkler working on wine... but I haven't touched PC size coding for quite some time now...
added on the 2015-08-01 18:51:54 by jix jix
I investigated the Wine issue a bit more. In the newest version from the git repository it actually works. It spits out lots of warnings, but it runs.

This is mainly due to the GetNumaHighestNodeNumber function returning a sensible stub value (always 0, so it will only take advantage of one socket in a multi-socket machine), rather than returning garbage.

Wine just came out with a new version - 1.8 - so I tested Crinkler 2.0 using this new version. It works great, with the previously mentioned caveat that in a multi-socket system, only the cores in one physical CPU will be used. Shouldn't make much difference for most users I guess...

So now you can again log in to your beefy server to do the crinkling. :)

Be aware that RVA forwarding may be different in Wine than on real Windows. For example, timeGetTime is forwarded to GetTickCount. For this particular case, it will probably work out well, but the other way around - when something is forwarded on Windows but not in Wine - will break.

I don't have such problem with version 1.4.

Also the size of the result is different on differeent Windows systems, is it due different versions of libraries or something else?

Am I right in assuming that you are using the TINYIMPORT option? Behavior like what you describe is sort of expected when using that feature. It builds a minimal hash table which has no collisions between the imported functions and other functions in the same DLL, but if a later Windows version adds a function which collides with an imported function, the intro may break.

To minimize the risk of breakage, Crinkler knows about all functions in commonly used DLLs in all Windows versions at the time of its release and avoids these in addition to the ones present on the build machine, but since Crinkler 2.0 is now more than two years old, some disrupting functions have snuck in since. Time to release an update, I guess. :)

There is some more discussion of the feature in this thread.

If you are not using the TINYIMPORT option, then you have found some really unexpected behavior. In any case, if you could send us your object files, the options you use when compressing, and the resulting executable when compressing on your machine, that would be very helpful.

Also I have issue with Windows 10 VS 2015

I will send you all the project, with the code ;) np.. Ijust need some time to prepare everything!

BTW it would be great to have some feature to use default linker, I have a lot of builds for one project and I am trying to automate the building process and as result I want to have a folder with all binary types..

for instance:

4kb slow 1920x1080
4kb slow 1280x720
4kb slow 1680x1050
4kb slow 1024x768
fast build 1920x1080
4klang CAPTURE only build
normal builds to check on different machines

a slow build takes about 2-5 minutes.. thus I want to run Batch Build and make a coffee... ;)
