You automatically play as Ryu and fight Ken. He has a very mangled piece of code as well as Ryu's. A (hold) = move Right D (hold) = move Left T (press once) = Hadoken Spacebar (press once) = Play Versus screen and Fight (Run this after the Intro finishes; try not to press it accidentally during the fight unless you want to redo the battle)
