I just thought I'd post and say that this game doesn't seem to work for crossover.
It loads up fine, the music plays but when you actually go to do any of the levels, it's just a black screen with the "HUD." You can't actually see the biker. You can hear and see how long you've been going, but no graphics.
I'm using a new MacBook perfectly capable of playing this game. If anyone knows how to get it working, please, let me know.
