Go to the Key Configure screen. Place the cursor on any of the L or R buttons. Press L1 + L2 + R1 + R2. If done correctly, the controls for the L and R buttons will be changed to camera view controls. You can now rotate the view freely, though the zoom function seems to be missing.

On the Loading screen, rapidly press X to change the color of the word "Loading."

At the character select screen, hold L1 + L2 + R2 + R1 to choose a fighter at random.

Here are some secret winning poses which are shown only when a certain character beats a certain character.

Kayin   beats Naru
Naru    beats Kayin
Chaos   beats Ellis

To play as Fo's ghost get all the secret characters and then put the cursor on the monkey guy(I forgot his name) and press X.When the fight begins you will be Fo with green skin and red eyes!

Once you have beat the game and unlocked all bosses, beat the game with Sho on "Impossible" difficulty, and once you begin playing again, the menu buttons will be outlined in red, when you play, most people have new and strange outfits and when you press R1 and R2 together, they do another very powerful move, and it's unlimited.

Clear the game with Naru, then set two or more of the shoulder buttons to special moves. Pressing all special move buttons at once performs a secret move. This does not work for all characters.

When the special move meter is empty, pressing all four special attack buttons will result in a super-secret move.

Pause a match by pressing START and map L1, L2, R1, and R2 keys to the Soul Bomb function. Resume the game and press one of the those buttons and the CROSS button at the same time to do a Soul Bomb any number of times you want.
