are there any alternatives to running it in dosbox as even when i try to speed it up with frameskip and increased cpu cycles, it runs too slow and i try in a pure dos install, when i get in game, it crashes

it uses the ultima 8 engine which means it should technically run through pentgram but it won't work that way either. i have an 850mhz duron, 384mb of ram and windows xp pro. CAN SOMEONE HELP?????
