Whenever Link is about to enter a door, the camera swings around so that Link and the door are centered on the screen. In some places, it is possible to get the camera stuck at this angle.
Walk up to a door so that the camera changes its position, then use C to enter first person mode. Stand on the right side of the door and hold up and right while looking to the left, so that the camera view starts to jitter. Once the camera is jittering, exit first person mode and immediately run backwards out of the door zone. If done correctly, the camera will remain at the same angle, and will not rotate around Link as he moves.
The camera will become stuck in place with the following exceptions:
This camera lock has no known uses at this time.
If you interrupt the skulltulla death animation with a bomb explosion, the skulltulla's dark corpse will never vanish.
Actors that push Link around without being pushed by him can push Link out of bounds while he is hanging from a ledge.
In Skyward Sword, it is possible to get a long jump attack by targetting something that is standing above ground that is higher than you. It does not give enough extra distance to have many uses in speedruns: its main use is in the Wisdom Room of Sky Keep where it helps to avoid using the double clawshots.
While the minigame owner only asks for 10 rupees, you actually need 20 rupees to play the Clean Cut minigame in the US 1.0 version. This was patched in later versions.
This glitch is famous and prompted Nintendo to release a patch. This only occurs on 1.0 versions of the game. After meeting with Levias, complete the Lanayru Song of the Hero quest. Once that is done, go back to the Lanayru Mines and talk to Golo again. This will set the flag that you have started the Lanayru Song of the Hero quest again, despite the fact that you've already completed it. This makes it impossible to start the other quests.
Contrarely to popular belief, the glitch is not related to doing the Lanayru Song of the Hero quest first. It can also happen when doing it second.
Trigger a textbox during the Zelda tutorial (by picking up a rupee, or activating the life tree seedling for example). When Zelda attempts to talk to Link again, it will trigger the textboxes with ids that follow the textbox you just triggered. This is a funny effect but it is unfortunately useless.
