48 Ocarinas

You need an empty save file, select it and choose a name.Slowly pull out the left side of the cartridge until the sound becomes distorted, when it does select 'end'.After the game finishes saving the data and takes you back to the select file screen, push the cartridge back in.Select the new game file and open it.During the starting movie when you see Link, if he has no sword or shield then you have done the trick correctly, if not, try again.After the starting movie ends Link dies straight away, when you come back you'll notice that Link has no life hearts, he also has no sword or shield.The item and mask screens are both completely filled with useable, working Ocarinas of Time, when you start you'll have one of these Ocarinas equipped to all three c-buttons (that is, the same Ocarina on all three buttons).Any writing that appears on the c-buttons or the B button will be rimmed with green instead of black, if you get magic power it will change to black.After you get turned into a Deku pressing B makes you pull out his pipes, this stops working after you get magic power.After you've finished talking to the Happy Mask shop man talk to him again and he'll teach you the song of healing straight away because you already have the Ocarina(s) of Time.If the game tries to give you any health or take any away you'll die.Destroyed bushes will drop bombs and arrows even though you don't have the Hero's Bow or a Bomb bag, if you collect some dropped bombs they will appear on the item subscreen, even though you don't have a Bomb bag, sometimes you may be able to use these bombs without having the Bomb bag, sometimes you can't. Collecting dropped arrows does not give you the Hero's Bow though.Any masks you get will overwrite the Ocarina in their place, so will any other items you get except bottles.Collecting four heart pieces will increase your live by one heart, the first putting you up to a total of one heart container, when you have one heart the game constantly makes the beeping noise that indicates you're almost dead.If you collect the missing part of the great Fairy then talk to her she'll give you magic power like normal, but, she'll also heal you, this of course kills you and when you come back to life you'll automatically start talking to her and, she'll heal you, you die, come back to life, talk to her etc. You are now stuck in this endless loop and have to turn off the N64 to get out of it.If you see her after you've got a heart container she'll give you magic like normal and you're free to walk away.Once you have magic you can take the Bomber's challenge, do so as normal Link and make sure the last Bomber kid you catch is the one in West Clocktown(this might not be necessary). Once you catch the last one the screen fades to white and then freezes, leaving you looking at a white screen, you'll have to reset.

Note: This trick is actually a way of duplicating a certain hardware "glitch" which takes place when the cartridge is not inserted properly or for some reason cannot be "read" properly by the N64. This "glitch" causes any saved files to not appear and if a new file is started all saved data is written as If this happens to you, turning off the N64, taking out the cartridge and then firmly reinserting it should cause your save files to reappear and your game to write data properly.
