When I try to play it,it will say:DOH! Set Display Mode Failed! 1280x1024x8.
1st of all, you should stick to one thread. 2nd, Williams Pinball Classics is a 10 yr old game. You should be running it in "Win98 compatibility mode".
3rd, the error tells you what the problem is - you're trying to run the game in an unsupported display mode. Try changing the settings.
