On the level select screen in multiplayer, tap up seven times to unlock a new stage and multiplayer character.

Put the game in a CD player to listen to the games soundtrack.

On the continue screen, where it asks Yes or No, use the D-pad to enter the code Up, Up, Down, Down, Left, Right, Left, Right. Each time you enter it correctly, the number of continues remaining will increase. If you're already out of continues you won't be able to do this.

Complete the following tasks to unlock additional options.

Option	How to unlock
Disable Powerups	Play 10 games (must return to menu 10 times)
End Credits on menu	Beat Normal Story mode twice.
Ghost Sheep	Play 30 games.
Hard Difficulty	Beat Normal Story mode.
Image Gallery	Play 40 games.
Music Gallery	Play 20 games.
Night Mode	Play 50 games.
Omake mode	Beat Hard Story mode.

When playing through story mode, have a friend (or two or three) hold the triggers on the other controllers. They must hold it right through the end of each story panel to the beginning of the actual level. They will then be able to control the associated computer player for that stage.
