Mario Kart DS Tips

PRB (Prolonged Rocket Boost) is a glitch in the game. You can go over rough terrain with it slowing you down. Mario Circuit 1 for example, you can go over the dirt on that level without slowing down. To PRB, you have to get a perfect boost (or close to perfect boost) and star snake right away (tips on snaking will be coming!). It's mainly used for time trials but you can use it for racing. But once you get hit, with a shell or anything like that, you are done.
