On win95, it straightaway says that the dll cannot start, and that's all. I don't have XP, maybe thats the only OS it works on?? This machine is win2000pro. The program tries to run but it goes at a snails pace. In the top left corner is a tiny coloured copy of the game but just dots, not graphics. The rest of the screen shows the game starting up and the demo running, but just black & white, horrible, and 5 key does nothing. I never saw a 3d image. The roms are exactly the ones specified with correct names and CRCs. It could be this machine as MESS doesn't work on it either. This computer is a celeron 500mhz with 512meg of ram.
