While playing a two-player game, press START then press SELECT, choose a different character, then press X.

When either player is teleporting in the blue ray, have the other player press START, then SELECT. If you're quick enough, both players will have the same character.

Hold R2 while executing these moves.

• Hellrain: Up, Up
• Hell Ball: Up, Forward, Down
• Hell: Down, Down
• Double Hell: Back, Forward

In the "option mode" when you start a game, go to the bottom and hit R1, R2, L1, and L2 at the same time. New options will be revealed.
