I have done a clean Windows 2000 install and tried to play Nascar4 after that. Unfortunately, there are some problems with this game and Windows 2000. Nascar 4 worked fine on my previous system which was Windows 98SE. I am unable to figure out why the game is not working properly and I ask you to help me if you can.
Nascar4 is very old game and I think that you are out of luck here. As far as know, Sierra is not supporting this game any more so you will not be able to find any patch addressing issues with Windows 2000. Only thing you can try is to update driver for video card and hope for the best.
