OK....for this to work you have to be pretty far in the game already. After the first tournament to decide what the teams are, your going to travel to New York and challenge White Tiger X. When you pick who your going to fight with pick Tyson then whoever. Battle the first person and beat him and you should get 100 EX. After you beat him save the game and then quit. Turn it back on (Or just go to Exit Game in the options XD). You'll notice that you have to pick teams again so pick Tyson again and repeat this process throughout the whole tournament. There's also a glitch. After you beat a team go to the airport and fly to New York (it's supposed to be Japan but I assume they didnt think that through). You'll notice your back home. Go back to the airport and go to "New York" and you'll end up at the first tournament facing White Tiger X. But the announcer will say another team like the Blitzkrieger Boyz and that you'll be facing Kai, and you'll start walking on air as if your in the arena about to battle... XD I'm not sure what this does to your game if you keep going because I never went that far...
