You won't like this answer, but here it goes. The N64 rom performances vary from computer to computer. Some of them will work perfectly for you, and others have crashing, sound, graphic, or combination of those issues. Thing is, not everyone experiences the same problems with the same games, and some people have no problem with games that many do have problems with. In the end, it all depends on your computers capabilities. Specifically, it depends on the capabilities of your sound and graphics cards. The part you are not going to like is that the only way to fix the issue is to purchase a better sound or graphics card, or play the game on a computer that has one.

Second, I'll move this over to the RGR forum, since it isn't specifically about the game itself.

EDIT: I'll close this since there has been no reply or activity on the thread for a long time.
