Fight as Ryo Sakazaki
First, beat Ryo (it would be a good idea to save this fight.) After the game ending,look at the demo game. When you hear the "Fight!", enter this code: UP, A, LEFT, A, DOWN, A, RIGHT, A, UP, A, UP, C, RIGHT, C, DOWN, C, LEFT, C, UP, C. If this code is entered correctly you will hear Ryo's voice. Then you can push start button. Note: Ryo is only available in P1 VS P2 mode.
