At the main menu, quickly press Triangle(2), Right, Circle, L1 or Circle(2), Right, Triangle, L1 to enable the EX Option. Use that option to set "Original Mode". Then, choose versus mode and have player one select both of his or her characters. Player two should then select the same two characters in the opposite order that player one used. Now start a game and press HP to switch teammates. The EX Option menu may also be used to keep the power meter full. Note: For the Japanese version of the game, at the main menu, quickly press Square(2), Right, X, L1 to activate the code.
