Bio Freaks (Cheat codes)
Immediately after powering on the system, press C-Left repeatedly until you hear the sound of laughter. Now a date on the title screen will indicate when your game was completed.
During a match, hold Left and press Start. Hold Down and press Start to return to the default view.
Pause the game during a match, and disable shields. Then, resume the game and hold A while attacking. Your character should be able to do a significant amount of damage without being hit too frequently.
During a match, press C-Left + C-Right.
Pause the game, and after a few minutes a screen-saver will appear with the words "Game Paused" and flashing lights.
