Second Player Time-Out
Normally, Player 2 cannot pause the game to alter the settings; just Player 1. However, you can enable Player 2 to do this. On Controller 1, press A and B and hold them, then reset the console. Now, if Player 2 shouts to his internal microphone for several seconds, a time-out engages.
