in the compo i thought it was nice but missed something... now i know why ;P
its a shame it would have ranked way higher if it had the sound coming out correctly.
protip: if you need another dos-setup than the dosbox standard one just deliver a config file (and maybe a convenient .bat too) the orgas can use instead.

holy fucking cow, this is insane! shame that it was ran without sound in the compo, should have been ranked MUCH higher! :)

seems to not working on real pc? (hangs under clean dos, broken sound and crashes under windows)

To elaborate a little bit more: frag & provod can't be blamed for the fuckup *at all*. In the readme file, they very clearly specify what's up. It was all our (specifically, my) fault that we didn't follow the instructions. That was unprofessional. My "sincere apologies" comment yesterday wasn't just an empty phrase, I really mean it. I perfectly understand that this costed this entry quite a few positions in the ranking, and I feel deeply sorry about that.

Damn with the synth music added it's a hell of thing, Using some little bat file to setup certain dosbox settings that can be changed from console makes things easier for orgas.

Somehow we forgot to add sources, will update archive soon.
Code is far from optimal indeed, we stopped working on it just before the Deadline's deadline.

@KeyJ Probably it was safer to provide config file, sorry!

@TomCatAbaddon I wasn't sure about fs in real dos, yes, it must be set, thanks for fixing it!

There is some logic in why we used obscure covox and not a speaker:
- this is party version, it was meant to run in dosbox, and sound quality of covox in it is better.
- sound capability of real speaker depends on its physical properties and can vary widely (or be completely awful in case of piezo buzzer).

I planned to do final version with slightly better visuals and optional speaker support.

@wbc: worked for me USBboot +FreeDOS +VolkovCommander
But i'm afraid of the intro use the memory very freely. I don't understand it in detail.

@frag: You are right about sound quality... And please do it! Make your final version! I really want to see it :-)
oh-kay!!!
rulez added on the 2018-10-09 15:06:31 by gman gman
@wbc Here is the fix, instead of this
Code: MOV WORD [FS:BX+20H],IRQ MOV [FS:BX+22H],CS MOV FS,[SI] MOV SI,ZAK2 MOV AL,13H INT 10H PUSH 09FF6H POP ES

put this:
Code: mov fs, [si] ;fs = 0x34B0 mov si, sum_deltas mov al, 0x13 int 0x10 push 0xA000-0xA pop es mov ax, 0x2508 mov dx, IRQ int 0x21

And it's two bytes less too.
Sorry about this :(
added on the 2018-10-09 15:11:34 by frag frag
yeah, i did almost the same (replaced direct IVT write to int0x21 call + fixups) and it worked fine on real DOS (with subtle sound differences, caused by LODSB with dangling SI?) then sent that fix to provod :D
also you can omit CLI and PUSHF/POPF in interrupt handler, since CPU stores flags onto stack and disables interrupts before entering ISR (so minus three another bytes ;)

Wow, thanks for all the comments, I really appreciate it!

@KeyJ, @v3nom: Apologies accepted. FWIW I also do feel I'm to blame here too. In my submission message I haven't made it explicitly clear that we expected latest vanilla dosbox release (0.74-2) with default settings (except for the `cycles=max`, which is required for smoother video, and does nothing to sound). I was ignorant and didn't expect that there are other popular dosbox forks that could have different default settings.

TL;DR: This intro uses Covox/Disney Sound for sound output, which is kind of an obscure thing. Vanilla dosbox enables it in its default config, but dosbox-x fork that was used at the party has covox disabled, hence the confusion.

Covox is just bunch of resisters dangling from an LPT port, which essentially makes sound output just a matter of writing unsigned bytes into port 0x378 at whatever desired sample rate. This is obviously simpler than going full-SoundBlaster, because it remains yet to be discovered how to initialize SB in a sane amount of bytes ;).

@TomCatAbaddon, @wbc\\bz7: Wow guys.. frag already acted on your feedback, but I'd also like to express my appreciation. Thanks for your help!


I am planning to do a short stream about sound synthesis in this thing as soon as I find a free time slot for it (probably tomorrow 2018-10-12 around 22..23-ish Tokyo time). Although it is not particularly clever or anything, there are a couple of things that I'd like to share.

Plain awesome! After finally hearing that ace tune and looking at the code i freezed in utter disbelief. I had heard that there was a "trick" to play wave files on msdos, and i tried several things i found on youtube but nothing worked. I read myself into PWM which was quite easy to understand, but couldnt get it to work. Heck i even tried to "volume modulate" MIDI which didn't work as well. Then, months after, THIS comes along and works so flawlessly and sounds beautiful ♥ Hacking yourself into the IRQ table like that is a very bold move though ;) Of course 0x2508 is a better way, while 0x251C is even better since it save 4 bytes with not needing to tell that the interrupt is done. Likewise, if you just need a lowbyte for the first timer, you can set the appropriate mode and save 3 bytes there. And there is more!

Anyway this is a real boost for the whole sizecoding scene with regards to sound, since many are tired of MIDI or just love to hear a proper chiptune. And i can continue to explore amplitude modulation like for example in Coral Reef. Thanks to "somehow" i recently experimented with basslines with reverb and overdrive (see here) I like where this is going (as a whole) You should defnitely write an article - and paste or link that to sizecoding.org =)

@HellMood
Thanks!
Good trick with 0x251C!
Synth was further optimized and now we have ~40 bytes to spare.
We decided to invest it in more complex melody and visuals.
Please wait for the final version.

unfortunately it will make system time\date clock run forward like crazy, at least on real PC (nevermind :) but shaving more byte is worth it imho :)

good sound, nice visual, but i didn't catch what hellmood is talking about... what is new? viznut introduced covox to the sizecoding scene in 2011... in 125 bytes.

and I had several intros with pwm sound in the past two years: plasmifier cover, tctronic, 256unlimited

frag has right, the covox sounds better, beacuse of the 8 bits sample, pc speaker able to do only 6 bits... moreover DOSBox has an annoying repetitive high pitch.

Luckily my HP Desktop has a very good and loud PC speaker, but otherhand it has no parallel port for a covox extension (yes the usb adapters don't work, but i could buy a pci express LPT card for that).

as I heard Kuemmel is also thinking of a sizecoding.org article in this topic... the more articles the better :-)

btw
has I missed provod's stream? where could I rewatch it?
holy fuckin shit
rulez added on the 2018-10-16 20:31:01 by Negrostrike Negrostrike
@Tomcat: No worries mate, i'll explain myself better =) On my research earlier, i found the "covox intro" (the 125 byter) too. While that was interesting, it sounded quite awful, and i didn't realize that AM could be done with that. It appeared more like some kind of fancy random noise done in FM. Your recent entries with sound, improved a lot from you first one (which i think i stated in the comments to all of these), while they still sounded like they could have been done with FM. I thought so, because i did SpeaCore 128b in 2016 already, with arguably better sound and graphics than the covox intro. So i thought you experimented with FM too, since that is what the native PC speaker is all about, and found alternative ways to something which sounds like kicks or snares. It didn't really sound like it's AM and i never looked into your codes. I should have, maybe i would have noticed the technique ;)

But this one here is different. You immediately here it's AM, it's polyphonic, harmonic, and has some kind of reverb, which is kind of impossible to do in FM. Well, and it's really beautiful ♥. The only thing i could easily in FM do is a decent basskick, along with some psycho acustics to fake polyphonics. Maybe it's still possible to do proper sound synthesis in FM, but i wouldn't know, and i didn't find any good sources on that.

Kuemmel already contacted me, and i'll happily integrate my knowledge into that article, we all should. Polyphonic harmonics and bytebeats are really just the start. Once we have an optimal AM boilerplate, we can go really bonkers with snares, kicks, reverb, delay, wobble basses, overdrive and whatnot =)
added on the 2018-10-16 22:24:55 by HellMood HellMood
@HellMood: only two intros of mine have similar sound to speacore (life&life and teacups). and those kick drums are very sensitive to the speed of the PC :-()

about the pc speaker:
Yes, the default PIT mode#3 is about square wave freqs. But check the PIT mode#0, it is about the PM, you can use it for playing digitized sample.
@TomCatAbaddon I have yet to stream (and write an article for that matter). Maybe later next week. I will announce it here.

int 1c sounds as a really great trick
but unfortunetly int 1c didn’t work for me under FreeDOS

and please notice if the whole bios int 8 code + your int 1c code together doesn't last same long each time when it runs, then the sound quality will be a bit worse.
