The Legend of Zelda: Link's Awakening Cheats

This odd secret allows you to get to an alternate version of the dungeons, complete with walls you can swim through, invisible walls, strange looking enemies, and other oddities. You can even swim off the sides of dungeons into different ones.

You can actually do this as soon as you finish the first dungeon, but you really need the flippers, as you have to swim all over the place.

Go the the boss room of the first dungeon, equip Roc's Feather, and fall down one of the holes in the side. As soon as the screen switches to the side-on view, hold up on the D-Pad and jump using Roc's Feather. If you did this fast enough (and held up... it's necessary for some reason), you'll jump up off the screen into what looks like a room full of impossibly placed locked doors. Move around a bit and you should soon find yourself in a dungeon with the cheat activated. To get back to normal, just enter some stairs.

To warp to the other side of the next screen, press select in the middle of the transit of screens.

There is a way to get a Level 3 Power Bracelet, but it has the same strength as the Level 2 Power Bracelet. It's actually very simple. You first must be inside level 7, Eagle's Tower. Get on top of one of the ledges on the first floor. Now enter a screen at any direction, while doing the Warp Across Screen glitch (pressing select as you enter the screen). If you did it right, you'll be at a location with a treasure chest at the top left of the screen. Walk over to it and open it up. It will look like a regular power bracelet, but when you look in your inventory, it will say L3.

When fighting the Dodongo Snakes in Level 3, kill one snake normally and then leave the room by taking the stairs next to the door on the south end of the room. When you reenter the room, the other one will be dead and the fight will be over.

You can get a Level 2 Power Bracelet in Tail Cave By following these instructions:
1. Go to the room before Nightmare Battle in Tail Cave and go down stairs.
2. Go to left screen down in the side-scrolling area.
3. Screen warp from left screen-to-right screen.
4. If done properly, you should land on a pillar. Push right, and you should jump off the pillar, and end back up in the room before the Boss Battle.
5. You now can walk through stuff.
Now to start getting the bracelet.
6. Go south through the doorway.
7. You should hop from the sky onto the next room. Walk along the edge of the wall and go into the west doorway. If you go too far into the wall, you'll drown.
8. In the next room, go straight to the west, but go AROUND the obstacle to the west doorway and enter it.
9. Go through the blocks in the next room and through the north doorway.
10. Go up in next room and hop over the holes and the keyhole up to the elevated platform.
11. Go through west doorway.
12. Go in front of chest and open it. You should get a Level 1 Power Bracelet. (You can stop if you just want LV 1)
13. Go east a screen.
14. Now come back west and open chest again. Hiya LV 2
Now save and quit to lose the wallwalker glitch. Congrats, you're strong now.

At the start of the game, go down to the beach, to where the L-1 sword is. Don't pick it up! Instead, use the screen warp glitch to go west, and hopefully the sword will have floowed you onto the next screen. If it does, pick it up. If it doesn't, go back east and try the screen warp again.
After you get the sword, go back to the screen the sword is normally in, and you'll see a shield. Pick it up, and your shield will be downgraded to Level 0. It works just like an ordinary shield, except it is invisible.

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. Link will fall into the water, and when you come back you will be at the top of the map near the bridge. you will fall again, but this time you will come back on the bridge. a warp point is nearby, so you can come back whenever.
