Not sure if anyone can help me here, but I want to run Zone Raiders in 640x480 resolution on a Riva TNT2.
Obviously since it's not a UniVBE supported card, it doesn't load a supported driver. I've tried using the UniVBE modified drivers, but it still says "Video mode not available".

I have the same issue with Mortal Kombat Trilogy. It loads with the modified driver, but remains in 320x240 resolution.

The PC I want to run it on is only a Pentium 2, so too slow to run it in DOSBox. I'm running it Windows 98SE, but could also run it in MS-Dos Mode if required

I'm not sure if I'm using the modified driver properly, or if I must use it in conjunction with something else, so any advice would be much appreciated.
