Zelda II: The Adventure of Link Glitches

Glitch Town
1) Go to Darunia town, have enough magic to do 'Jump' and 'Fairy'.

2) In the first or second section jump on the lowest house using the spell 'Jump'.

3) Jump from house to house until you find a house that is high enough so when you jump up your body goes off the screen. Now get ready to use 'Fairy'.

4) Jump up, then while Link is off the screen use 'Fairy' and press left or right.

You will fall like you've fallen into a hidden hole. You will reappear in a different town, that isn't any of the other towns. When you try to go into an open door, it will take you back to the beginning of the town. What's even stranger, the sign that tells you what town you're in tells you something about a magic key... or something. Stranger still, when you leave the town, you will be stuck in the water, somewhere below the valley of death.

Fast Experience
You need at least one character in your cart who has beaten the game.

1) Have the old character beat a palace, then quit the game (pause and press Up+A on controller two).

2) Save the game.

3) Immediately begin playing with your new player.

When the game starts, his experience will ZOOM up.

Odd Warp
1) In palace two, three or five, find the room with falling blocks that build a wall, filling up the entire screen.

2) Let the blocks fall until a solid wall is created.

2) Break away some of the blocks to form steps and get onto the very top of the wall.

3) Use 'Fairy', press A to transform then press left or right.

4) You will appear on top of the palace, use 'Fairy' and press A again, then press left or right.

You'll fall onto what looks like the first palace, the layout is the same but the colours/textures are those of the palace you were just in. Once you leave this palace you'll be outside the palace you were in to begin with.
