The Legend of Zelda: Twilight Princess Cheats

Sinker Lure
To obtain the Sinker Lure you must first catch a Hylain Pike, Hyrule Bass, and a Ordon Catfish in the fishing hole area with the lure rod. After you have caught one of each you go to the south east corner of the water closest to the house and take out your Fishing Rod(bobber). After that you will catch the Sinker Lure. Make sure Hena doesn't see you use it or she will take it away.

Quiver Upgrades
To upgrade you arrow capacity, you need to play the "STAR" game located in the large tent in Southeast Hyrule Castle Town.

Big Quiver (60 Arrows): Beat "STAR" game lvl. 1. (Clawshot Required)
Giant Quiver (100 Arrows): Beat "STAR" game lvl. 2 .(Double Clawshot Required)

Wallet Upgrades
To upgrade your wallet size to carry more rupees, you need to catch Golden bugs for Agatha in Hyrule Castle Town.

Magnetic Ceiling Glitch
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.
