Kega & CRT_EmuDriver Help

[webodan]

Hello,

I've got an HD 4350 under Windows 7 and CRT_Emudriver with default video modes and I can't make Kega Fusion switch video modes properly, I tried modifying fusion.ini with the parameters listed on winmodelines' website but it still doesn't switch properly.

I can only see a quarter of the screen and it runs in 480i, I've also tried replacing the 320x240 and 320x224 modes that it came in default with the ones made for megadrive listed on that same website and the screen went away when Fusion switched to them, it became fuzzy and couldn't run. I'm certain it works nice because I could run 256x224 and 256x240 but not 320x240 or 224... I don't know how this super resolution thing works under 7.... in XP everything I use worked but I can't use it under my current hardware.

I hope someone can help me.

Does 320x240 work fine with Arcade OSD?

Hello Calamity,

I've tested again after reinstalling the driver and both 320x224 and 320x240 work in arcade OSD but not in kega no matter what i tried

Thanks for your help

All right, so I've got another HD 4350 because the one I had stopped outputting video, this one runs much better but it still has the same issues in Kega (320x240, 320x224) and in Meka as well, as i've just tested Master System (256x192, 256x224) and none of them work, they can't be outputted by neither emulator and the image just goes away when they switch to full screen.

I can set them in quickres or arcade OSD, but it will just break when running on any actual emulator. I've also tested the video modes from winmodelines tutorial because I thought the emulators used slightly different versions of those video modes, but to no avail. I'm severely limited on my options as a result

What happens if you set the desktop to a progressive resolution before launching the emulator?

[webodan]

I've set the desktop to 320x240, then launched Kega, then Meka in auto fullscreen with a rom loaded. The screen went away again. It goes crazy for a split second and then black screen. I have the video modes from winmodelines installed at this moment. I've got a backup of the original modeline txt in case we need to test with the default ones.

update: I've restored the backup to test this in depth, so, setting a progressive mode before the emu fixed cps3 (that one also couldn't work, so at least that's one that works), but not kega or meka. Same issue.

[Calamity]

I'm afraid this is a compatibility issue with Kega itself and modern operating systems. It uses DDraw and this api is partially emulated, probably starting with Vista. There are some compatibility options at the top of the ini file, try your luck. I'm trying it here, Windows 8.1, stock video drivers, and it won't go full screen either.

Finally! I've made it work by setting a progressive video mode first, maybe some settings were borked in the emulator itself or I don't know, because at my first tries it didn't work, maybe I wasn't setting a progressive one, well whatever.... I've set a progressive mode as default for the desktop and now it does switch in the emulators. I'm pasting my settings in Fusion here (the only thing I don't like is that it has a small blue letterbox in the upper and lower sections of the screen)

Fusion.ini:

;---------------------------------

ForceCompatibleGFX=0

VistaAeroIgnore=1
VistaNoWndVSync=1

Mode256x480=256,480,60,50,256,480
Mode320x240=320,240,60,50,320,240
Mode320x480=320,480,60,50,320,480

So yeah, I can't switch from interlaced to progressive using an HD 4350 under Win7 without it dying, it would do great for an update if you fix this.

Thanks a lot for your help and for these wonderful drivers Calamity!! 

Oh yeah, also, under Win8 you need to apply configuration fixes to the ddraw dll to make it work properly, check here http://classicgamefixes.wix.com/home#!kega-fusion/c4dr

(stuff like this is why I installed windows 7 instead)
