Title: CRTEmudriver win7 other emulators
Post by: wman on February 07, 2015, 09:50:55 am

So i just made fresh instalation of win 7 x64 ultimate than instaled crt_emudriver_13.1_1.2b_w7_64 and groovymame.In vmmaker i have limited total modes to 90 to avoid hyperspin issue.Than i tested the setup and i have groovymame workin with all the low resolution no problem here.

I have ati radeon hd 4350 video card conected to pal tv.

But here is my problem when i try to run other emulators like snes9x, fusion, epsxe etc. and set them to 320x240 none of them switch to that resolution and crash fullscreen.I have tried unninstall the driver or reinstall.Ran vmmaker again but with no luck.

So if anybody have any info on this i would be grateful...

This is probably because you have your desktop set to an interlaced mode while the emulators are set up to use a progressive mode, and besides they're using DirectDraw. This is actually a bug in Windows 7/8 and DirectDraw.

Only workaround would be to use a script that sets the desktop to a progressive mode before invoking the emulators, then switching back to the interlaced one on exit.

It's that or using GroovyUME for those systems.

Thanks Calamity

Im about to build new machine for groovymame and emulators with ati radeon HD 4890 so i assume i would still have the same problem or does anyone else experiencing this ? I would be glad if you point me to the right script that would be useful.
