Hi! I want to watch some C64 demos on my Windows box (Vista Home Premium 64-bit).

I have created a 50Hz 1920x1200 mode in NVIDIA Control Panel. This mode works fine for the desktop and in WinUAE as well. But for some reason neither CCS nor WinVICE allow me to select this mode. It is as if the mode does not exist. Only 60Hz and 59Hz are available.

Can anyone suggest a good C64 emulator which is able to use a custom 50Hz mode? Or perhaps I am doing something wrong somewhere? Any suggestions?

Well, my solution at least for the atari emulators I tried so far in windows is: Powerstrip.

I set up a custom resoultion of the resolution I want to use (say 640x480@50hz) and leave powerstrip running. Then I run the emulator and when 640x480 fullscreen is selected, powerstrip forces it to 50hz.

That way I have succeeded into making steem and atari800win achieve smooth scrolling with the SMALL price of my eyes hurting like hell from the refresh :)

(also, I use that coniguration to drive d/scaler so I can use the same monitor as a monitor for my megaste using an old bt848 capture card - still 50hz refresh rate)

hello ggn, u use that on a lcd monitor?

Get a clue. LCDs are utter shit for anything but watching movies, and even then CRTs remain supreme. But go ahead and buy crispy pixels shit like the rest.

'It's wide. And it's flat.'

sink, nah, CRT. I dunno if LCDs can do 50hz.....

If you ever need to do this on in Mac OS X, I found SwitchResX to do just what I wanted: create a 50 Hz screenmode and have it available in the normal system preferences.

sure crt is better :), i agrée !

Photon: a plasma screen is a solution to that problem :)

What about laser screens! That's the way of the future! Laser!

Get a CRT and a real C64 ftw.

photon, well i'm pretty happy that my laptop doesnt have a crt.

I do have a real C64, but it is stashed away very far from here... And I don't have any equipment for transfering demos onto C64 floppies (or any C64 floppies for that matter).

Also, not all LCDs are bad. The one I have here has the ability to simulate the flickering of a CRT in order to achieve perfectly smooth scrolling. It actually works pretty well. In other words: The monitor is not the problem. :)

The problem seems to be the emulators, since they refuse to use the 50Hz resolution in fullscreen, even if I run the desktop in 50Hz.

What is the difference between Powerstrip and custom resolutions that could make a difference in this case?

Hmm, now it suddenly works in CCS. I am absolutely sure it didn't work before... :)

Oh well, now I can see C64 stuff (semi-)properly. :-D

Run it at 100Hz ;-]

an lcd screen that can switch frequencies? wtf? model id or it didnt happen...

Havoc, the analogue logic in them can usually scan at multiple rates. My Macbook Pro LCD was happy to run in 50 Hz anyway, so is my Eizo screen I have for the Falcon.

i was referring to the panel itself.

havoc: It's a BenQ FP241W Z. The special thing about it is not that it can sync at 50Hz - lots of LCDs can do that (but then again, lots of LCDs can't). It's its so-called PerfectMotion feature, which causes it to flash once per frame rather than being constant on, just like a CRT does. The result is a much sharper smoothscroll than what you can usually get from an LCD. Or from a CRT at 100Hz for that matter. :)

ok that's good stuff indeed- but it's a better approximation, not an ultimate solution i guess ;)

I like the CRT zealots. The remind me of Amiga users.

mirror, mirror on the wall...

"Should "Edge of Disgrace" by Booze Design be in the all time tops? It is about time to get a C64 demo in there."

Well, duh. ;)

Actually I also own an Amiga (3 IIRC)

Many laptop screens are actually pretty flexible when it comes to scan rate... Try powerstrip as ggn suggested if you want to try
