As you probably know, the file select screen keeps track of how many times you die in the game. To die and have it not count against you, quickly press A, B, Start, and Select as Link is spinning around before he falls down, and select Save and Quit. The game should reset. Now load up the file you were playing, and you should continue as if you lost, only the loss will not register on the file screen!
OK, go to the screen above the screen where the first sword is found (at the beach) use the screen warp glitch and you will be in the water.
