Top Inept Opponent In Piranha Challenge/Everybody Misses Luigi_1 8015B16C 9955 With this code, you'll win the Piranha Chanllenge easily, but if you're going to play on another game, such as the Tournement Mode, when you swing, you'll miss. Nobody will win anywhere.
Top Mario On Drugs Mode Ash_link 80153537 001F Go to anything (Exhibition, Tournament, Etc.). Make sure you have a GS on Mario tennis and put on this code (it may not work for earlier versions before 3.3) Enter the code in and enjoy!
