Clean Pause (any mode)
Pause the game as any player and press X + Y together (at the exact same moment, or else it won't work) on Controller A (to my knowledge, this trick only works on Controller A). Press X + Y together again to bring the pause menu back. Note that you can still change your selection to QUIT even though you can't see it, so be careful.
