DOS Games Discussion

I have recently bought a copy of X-Com: Terror From The Deep, I can install it and run it fine. But i Get this error after a while running the game:

|The NTVDM CPU has encountered an illegal instruction |

|application |

I am running it using windows XP. Can Anyone help?

I've played through this game on dosbox fine: just make sure to turn the cpu cycles up a lot.
