Playing Super Puzzle Fighter and tired of playing as Dan (or one of the regular characters)?
Well, then I've got a present for you!
Start the game as Player 1
Then, hold down the Start button and press Down, Left, Down, Left, Down, Left, Down, and then press and hold Left on the Joystick (while still holding Start, remember). While holding all these down, press one of the Action Buttons to select Morrigan. Done right, she'll turn into Akuma!
Who cuts a much more imposing profile.
And should make the game a little more fun.
