Note: This only works with Super Saiyan 4 Goku. At the moment Super Saiyan 4 Goku releases the Spirit Bomb and it has passed his fingertips, press Start. Then, go to "Continue Game" and the Spirit Bomb should have at least a little rectangle covering it. If timed correctly, the entire Spirit Bomb can become a big block.

Walk on wall:
Note: This only works on planet Imecka. After you fight ten of the eleven Imeckian soldiers in the very first part of the level, make sure that you are all the way to the right of the screen. Defeat the eleventh one, then hold A and immediately press Right, Right, Up, Up after your character has dashed right. You should be able to walk on the wall. Be careful; some enemies are also able to walk on the wall. Note: If you switch characters, this glitch will no longer be in effect. Also make sure not to get too far down the wall or your character's feet will touch the floor and exit the glitch.
