Atari Karts for the Atari Jaguar. There are four levels in Atari Karts: Beginner, Warrior, Miracle, and Jaguar Aces. The first time you play, you will only be able to choose Beginner. The next challenge will be available once you complete the Miracle Race. Once you have completed a level, you can choose that level or any level before it when you start a new game. You'll have to jam on the speed to make it through them all.
