Here'a a neat little cheat that can be inflicted on horrible little brats. Perform a Babality then, before your opponent changes, hold HP, LP, HK, LK. Your opponent will instantly return to normal size and explode in a blast of blood and bones! That's no way to treat a kiddy, you know.
If you do not feel like putting in the extra options cheat to get a stage select, just hold up and start on the player select screen. If you did it right you will hear a boom and the screen will shake.
All these codes must be entered in the normal controller settings, otherwise they won't work. Press the following buttons at the storyline screen: C-Left, C-Up, C-Right, C-Down, A, B, B, B, A, A. This code will give you 2 extra options in the options menu: the blue option and the red option.
