@mbrett ummm... do you have the game files in the C:/Games directory?
I've never used that program on the Pi, but I'm pretty sure the actual game wouldn't be supplied from the experimental menu since providing roms is a bad thing in these parts. You probably need to get the game somewhere else and put the right files in the right place.
You'd probably need to look for instructions on which versions would work with it too since there were quite a few.
Good luck man. That was an AWESOME game. If all else fails, you should try the PSX version if you can find the image. I actually prefer the Playstation game over the DOS game.
