After your game is over and the Continue Screen is counting down, you can increase your continues up to nin by pressing UP, A, and B simultaneously. At the same time, press button C for every extra continue you want.
To play with Krauser, Laurence, Billy or Axel, on the Takara screen, do a ''Power Geiser'' inverted move + B (directional pad, down, down-right, right, down-right, left + B). If done right, you will hear a Krauser's voice.
Now you can play in the survival, and v.s. mode.
To Play in the arcade mode, on the select fighter screen, put the cursor on Mai, and press down + start and right.
Complete the game either with the normal or hard difficulty level without using a continue.
Highlight the "Point" option in the "Control" section of the options menu for either player. Press and hold B and left until it reads 0.That player will now have to win 99,999 times to win (effectively making it impossible for them to win). This code works for either player, but only in versus mode. "1P" and "Survival" modes are unaffected.
