Two players can now compete in a game of "Mercy". Press the A button when
the title screen appears and go to the Options screen. From there,
choose "Practice" mode and then choose your fighters. Once in the
arena, move your fighters to stand facing each other, then push A and
B simultaneously on both controllers. Your fighters will be holding hands,
trying to push each other Down. The two players will have to push buttons
A, B, and C rapidly and faster than each other in order to win. Whoever
loses will fall and get a knockdown!
