Get All Emeralds

Start by accessing the level select menu, then navigate to the sound test in the bottom-right corner of the screen. Play sounds 04, 01, 02, 06 in order, and the "emerald-collected" sound should play. All emeralds will now be collected and the player can turn super by collecting 50 rings, then pressing the jump button twice.
