On controller two before the title screen appears, hold L + R + Z. Keep those buttons held, then on controller two when "Push Start" flashes on the title screen, quickly press and release Up + C-Down.

Note: The timing of this code is particularly sensitive; all buttons must be pressed and released at exactly the same time as indicated.
