Amazing Game. After so much years, I never complete the game because always have some bugs and crashes.

If some one know how to run this game under Windows XP without bugs let me know. I try using virtual PC and operating system Windows 98 , but the bugs are still there. The game just freeze at some point and the only think that I can do is only to move. If someone know how to resolve this let me know. I still want to play this is amazing atmosphere and idea that lack in todays **** games.
