The Legend of Zelda: Twilight Princess Cheats

This can be done wherever there is a magnetic ceiling, such as the first one encountered in Death Mountain Mines.

First equip the boots to the D-pad but don’t put them on. Go under the magnetic field and equip the boots. In mid flight up to the ceiling press the - button and put an item where the iron boots were on the D-pad, and make sure the Iron boots are not anywhere on the D-Pad. Unpause the game and finish flying onto the ceiling. You should be on the ceiling with the Iron boots off and you will stay there and be able to walk faster.

To get down walk off the magnetic part of the ceiling or equip and unepuip the Iron Boots.

First, as a wolf, play PLumm's minigame with the fruit and crash. Then, turn back into a human and turn to the water behind you. While swimming in it, equip the hookshot, and while it is held out, strafe tothe side and through the wall. If it works, you'll be swimming through the wall. Keep swimming until you flall and die. Now, as you wake up, Plumm will come back and ask to to play again. Say yes. Then crash at the beginning again. You should wake back up in the beyond-the-wall area from before, but you can stand. Turn into a wolf and jump into the waterfall. Then, you'll wake up in front of Iza's assistant. Say yes, and you'll go to her cabin. The boat will take off without you, and you'll be a wolf. So now, warp anywhere you want, and you'll have infinite bombs.
Note: This ends when you turn off the game, sadly
