Glitches

Reach Death Mountain without the Power Glove, before you've even delivered the Captain's sword.

1. Once the blacksmith gives you the Captain's sword, go to the Death Mountain cave entrance south of the Miner's House instead of delivering it.
2. Lure the nearby bird so it's south-west of the rocks blocking the cave.
3. Stand in front of the rocks, facing south-west in line with the bird. As it charges, jump off the ledge into it. It knocks Link back on top of the rocks.
4. Walk into the cave and follow it up to Death Mountain. The rocks stay cleared from now on.

You can't use the sword yet and you only have three hearts, so throw pots at the Moldorms inside.

After Early Death Mountain, touch the Death Mountain weather vane, then let an enemy finish Link off. When you wake up at home, Ravio's shop is open and fully working, well ahead of schedule.

Carry on after Early Ravio's Shop: deliver the sword, go to the Sanctuary and watch the Yuga cutscene. When the game shows Ravio moving into your house, the Ravio who's already there is still standing in the middle of the room, and the two of them stay in your house for the rest of the game. Link even gets out of "bed" from behind the shop counter.

Skips most of the Skull Woods boss fight. Once the fight starts, run to the top of the room. When Knucklemaster tries to ram Link, use the Tornado Rod just before he hits. Link pops out of the dungeon next to Seres's portrait in Skull Woods.

In the room with the red and blue crystal switch, the Moldorms and a giant bomb, a boulder sits to the south. Stand on the red barrier beside it, hit the crystal switch from a distance so the barrier rises under you, then set a Bomb and time a Spin Attack against the boulder just as the bomb goes off. Done right, Link is launched over the southern wall. Walk along the top of the wall to the bottom-right corner and you come out by the gate to the final boss. The timing is very tight.

Early on, Ravio asks which sign you saw at the Eastern Palace. Pick anything except the bow, leave his house and get knocked out by monsters. When you're returned to the shop, rent the bow for 10 Rupees. You'll have the bow but no energy gauge, and you skip Osfala's cutscene by the Eastern Palace.

In Lorule's Death Mountain caves on the way to the Ice Ruins, stand at the bottom of the giant ice gargoyle's platform and let it hit you. Link is flung across the area, which is handy for reaching the Maiamai there.

In the Miner's House, pick up a rock, then press R. Link holds the rock with his sword and shield out. Hold R to raise the shield and the rock ends up stuck in his chest until you let go or throw it. It doesn't work if the sword and shield are already out before you pick up the rock.

Somewhere you can't use your sword, such as your house, try to block. Link goes through the blocking motion with no shield in his hand. It only works the first time in each area.

In Turtle Rock's staircase room, aim at the corner on either side of the stairs and hold L until Link starts dashing with the Pegasus Boots, then let go. He keeps running without ever crashing into the wall, until you stop him.
