Classic NES Series: Zelda II Cheats (GameBoy Advance)

Find a mirror in an empty house in Saria and take it next door.

If you fall off the side of the screen when you get hit, you won't die, even if your HP is
at 0. Stand very close to the edge of the screen, and attack from there. You can use this
to level up without the risk of losing your EXP to a gameover. Especially at screens with
jumping fish.

Find the Trophy north of Zelda and take it to Ruto.

You can bypass a forced encounter if you enter the tile while it’s being occupied by a
random battle monster. Instead of fighting through the forced encounter you will fight a
random battle. After the battle, you can simply step off the tile and continue.

Once you have everything else, talk to the man in the old ghost town of Kasuto.

Talk to the old man in Rauru.

Find the Water of Life behind a boulder in the swamp, take it to Mido.

Talk to the old man in Kasuto (you must hammer a tree in the woods farthest to the east).

Find the child in the origin of the river in the maze and take him to Darunia.

Examine the fountain in Nabooru then talk to the thirsty woman.
