I legally own the old DOS version of Primal Rage, and am trying to get it to run in Windows XP. I've tried everything I can think of (compatibility mode), but every time I go to play it, it says that "Primal Rage requires at least a 486 processor". I've tried using a DOS soundcard emulator as well, and I can't get it to work.

Any suggestions? I've tried using the SNES emulator/ROM, figuring I legally own the DOS version and would play it if I could (this may not be totally legal, but I have no choice), but it doesn't play all the sounds 100% correct, and I don't believe MAME has ANY sound in Primal Rage if I'm not mistaken.
