Fatal Fury: Mark of the Wolves Cheats

Complete the game with all your Skill Levels on AAA or higher.

You can start from either character and press left or right twice to select either sub boss / boss character.

Hold down the start button on the character selection screen for a random select. Press any other button to choose your character.
