Dragon Ball GT: Transformation Cheats

Play through Rudeeze until you reach the boss. After you destroy his stinger, he will be unable to attack you from a distance. At this point, simply charge your ki meter and fire a special attack at him. It won't cause any damage, but you should get about 30,000 points or so for doing this. Continue doing so and you should quickly gain a large amount of points, and in turn, zenie.
