*Prepares to type a long post*
Let's start with how I got out of the forest without the Kokiri Sword. I hope some of you have seen that forest escape involving the Business Scrub in the Lost Woods. If you haven't, don't worry; I didn't use that anyway. What I did was get Deku Nuts and make my way to the little hole you climb through to get to the Kokiri Sword. Due to some programming oversight, you're able to move if you use an item after opening up a textbox right after you get out of a hole like that. What I did in that instance was talk to Navi and use a Deku Nut, enabling me to move. Then, I had to blindly make my way to the exit; since the Kokiri was no longer blocking the exit since the textbox was still up, I was able to get out of the forest.
Now onto the more important glitches:
Infinite Sword Glitch: This is perhaps the most important of all the glitches I used. If you're near something you can pick up or open a textbox with (sign, billboard, person, bomb), crouch stab and try to press A to interact with the respective object mid-swing. If done correctly, Link's sword will have the slash mark that you see when you attack at all times, the vertical bars at the top and bottom of the screen won't go away, and you won't be able to fall off any ledges. It's called "Infinite Sword" because Link is in a constant attacking state (if you run near an enemy you can hurt it without swinging). This glitch is required for...
Bomb/Bombchu Hovering: This glitch enables you to reach places previously thought unreachable in certain circumstances (Forest Temple as kid). The easiest way to do this is face your back to a ledge with the Infinite Sword Glitch activated while holding Z. Then, take out your Slingshot/Fairy Bow, ready a Deku Seed/Arrow, backflip, and quickly pull out a Bombchu and shield with R. Link will block the explosion with his shield, and since the Infinite Sword Glitch doesn't allow him to fall, he'll stay in place. Note that there are better ways to do this and gain more height and distance with each Bombchu, but this is just the simplest and easiest way. Also note that this does not work on slippery slopes (more on this later).
Megaflip: This glitch enables you to do a backflip four times farther than your normal one. There's an easy way and a hard way: The easy way to do this is activate Nayru's Love. Then, take out a Bomb, stay a little in front of it so it doesn't say "Grab" on A, hold Z and R, and wait for it to blow up. Right when the explosion hits Link's shield, backflip (still holding Z and R). The harder way to do this is the same as above, except you don't need Nayru's Love and must instead roll into the explosion then backflip.
There are many more glitches I used, but it would take a long time to explain them all. If you want to find out more, head on over to:
www.zeldaspeedruns.comAs for the Longshot, one of the rooms you need to get to Dark Link has two slippery slopes, which poses a problem for the Bombchu Hover glitch because you can't backflip when hovering above one. Luckily, you can use the moving platforms in the room to hover normally. The problem is, if you happen to backflip and be above a slippery slope, Link will do a farther backflip, requiring you to start over. Additionally, it gets harder to keep track of whether you're above a platform or not since Link's shadow disappears when you're really high up. Since the room is so big, it takes about 45-50 Bombchus to make it across. A difficult task indeed.
