Glitches

The Legend of Zelda: Ocarina of Time
One famous glitch is the infinite sword glitch, look it up online for more details. This glitch makes your sword active, even though you're not swinging it around. You can walk close to a Gossip Stone, and it will spark up like it would have as if you were actually hitting it. This glitch is also effective on regular enemies. However, you can't jump off cliffs, and if you swing and attack regularly, you lose your ability to use the glitch, and have to repeat the steps of the glitch in order to use it again. There are also glitches that are involuntary, as in you didn't do anything to make it happen. Unless you use too many cheats like when your an adult in Ocarina of Time. The physics engine may be corrupted temporarily, and if you pick up a rock and throw it, it may float away and never return. Some glitches may be hazardous to your game, and do things such as freezing your game, or corrupting save files.

Twilight Princess
Twilight Princess has a large number of fantastic glitches that can aid you in multiple instances. There are certain glitches that are very humorous, and should be tried whenever you get the chance.

Cannon Room Glitch
This glitch was addressed directly by Nintendo, and plagues many of the launch versions of Twilight Princess. While Link is in the Cannon room in Kakariko Village, the player may be unable to exit the room if he or she saves the game while inside, turns off his or her Wii, and turns it back on again. Shad, who was previously in the room, will no longer appear there, however when the player attempts to warp the cannon, Midna will act as though a person is still in the room - however, Shad is nowhere in sight. When Link attempts to leave the room, Shad appears on a separate dialog screen, and asks Link where he is going. This makes it impossible for Link to leave the room by any means, as Midna won't allow him to warp and Shad will not allow him to leave the room.

Nintendo has stated that it will exchange the games for an updated version that does not have the glitch.

Arbiter's Grounds
Outside of the Arbiter's Grounds are two ledges with torches above them. At a certain angle, Link can climb up onto these ledges. If Link moves forward, or in any direction besides backwards, the "Falling" sound will be heard, and it will start you back at the entrance point with deducted health as if you fell down a hole.
