This glitch could potentially damage your game, because it requires cartridge tilting.
When you start the game, get the first stone. Then go to the spot in the forest where the path to the Gorons is. Slowly pull the left side of the cartridge out and move Link forwards until you walk through the rocks. Put the cartridge back in. Play the rest of the game, but never take the bridge entrance to Kokiri forest until you are an adult. Then, finally, go to the bridge, and you will receive the fairy ocarina as an adult!
