Play Akuma/Gouki: On the character select, place the cursor on Ryu for 2 seconds. Then go on T-Hawk for 2 seconds, then Guile for 2 seconds, then Cammy for 2 seconds and come back on Ryu for the 2 last seconds: now validate with the 3 punch buttons + Start, but slightly shift the pression on Start with the punch buttons.
