Real Bout Fatal Fury Special

Hold B + C when choosing one of the following fighters at the character selection screen: Billy, Tung Fu Rue, Andy or Blue Mary.

Highlight Billy Kane, then hold B + C and press any button.

Highlight Geese Howard and press Z. Geese will look like a ghost.

After Krauser, Geese will appear as the last fighter to face you. This only happens if you have a score of 1,000,000 or more after defeating Krauser.

Select Wolfgang Krauser in his normal color. Once you reach the last stage (your battle with Krauser), you will instead fight Shadow Krauser. Note: Krauser's name will still be shown.
