Alternate Mokujin sounds

To hear different hit sounds for Mokujin, hold DOWN on the D-Pad or joystick before a match in which you are controlling him. Mokujin will now sound like a block of wood when damaged.

Arcade History Dip Switches

While at the Press Start screen for any of the Arcade History games, hold the select button and you will be given a list of dip switches. You can use these for such things as changing number of rounds or unlocking hidden characters, such as Baek in Tekken 2.

Choose Victory Animation

After winning a round and you see the replay showing, pressing each button( [X], [O], etc...) will result in a different victory animation. This also works when the opponent wins.

Play in 'Devil' mode in 'Devil Within' mini-game

This allows the player to play as Jin in permernent Devil mode without having his life bar drained out. The devil bar will be considered as his laser bar. The downside of this code is that it kills of you opponents faster thus unable to reach a higher combo rate.
Note: You must clear Devil Within under Medium difficulty. Then start a new Devil Within or Stage Select.
