The Legend of Zelda: Twilight Princess/Glitches

Here is an incomplete list of glitches so far. There are always bound to be more in a game of this magnitude.

Game breakers

 * 1)  On some versions, if you save and quit after the Eldin Bridge cutscene, but before going into the twilight, you can not advance, and must restart your adventure.
 * 2)  On some versions, if you save and quit after getting into the room with the cannon, but not warping out, you can not advance, and must restart your adventure.

Game restarters

 * 1)  In the Hidden Village, go inside of the building that leads to the seventh Howling Stone.  Climb up to the second level, and try to climb the broken wall to the right.  You will, but then you end up in a permanent slide in two directions, requiring a restart of the game.

Sequence breaking/other

 * 1)  In some versions (USA Wii, first version for one), if you are in a magnetic field, equip the iron boots, then go into your inventory and remove them from your accessible list.  You will be able to move around quickly.  To return, assign the iron boots again, equip and then unequip them.
 * 2)  You can get through the first gate (leading to Faron Woods) by placing either Epona or some rocks on the right side of the gate, side hopping, and then rolling.  What you do from there may or may not freeze up the game.
 * 3)  In the Lakebed Temple, you don't have to release both waters.  In the second room with rotating platforms, you can jump to a pillar with pots, and clawshot to the door leading to the boss key.  A similar trick gets you back to the big room.  There, clawshot to the chandelier, and hang off of the edge.  Drop down (not onto the staircase) and you'll be on the platform leading to the boss room.
 * 4)  After returning all the Poes to Jovani, turn into human Link, and walk out the door.  It will appear that you leave from the diggable spot.
