CRT_EmuDriver + PC Games = How can I force 640x480i? (non-MAME)

[sofakng]

I'm using the CRT_EmuDrivers with my ATI 4890 video card and it's working fine for MAME and the Windows Desktop, but when I run certain PC games (for example, "Castle Crashers"), the CRT TV goes out-of-sync and looks like it's receiving a 31.8 kHz (480p?) signal.

Is there any way I can fix this?  Do I need to somehow remove the "invalid" (31.8 kHz) resolutions from the registry to force the PC game to pick an interlaced resolution?

Hi sofakng,

Unfortunately you can't remove those resolutions from the registry, they're built in the driver. Your best options are:

- Force your PC games into picking a resolution under your control.
- In case a game doesn't allow you to select the resolution it must use, find out which resolution it is using and override it with a custom one. A way to find this out is using a PC monitor which has an OSD to show the current resolution. In order to override it you must create a custom video mode with the same label (width x height x refresh). You can add this video mode to ReslList.txt, then run VMMaker to create the mode.
