Found this on some Nintendo site. Dunno if it's already been posted, but I haven't seen it in any other topics.
I'm not gonna tell you what happens, that'd spoil it. I'll just say Link faces off against an enemy you would never expect (no, it's not Mario). Just download and watch, it's only 3MB.
If you have a Gameshark (its UK equivalent is Action Replay Pro I think), you can use these codes to get the same results.
(the secret enemy replaces the guy trying to lift the rock in Kokiri Forest)
