What's new in 100%?

Light Arrow Cutscene Wrong Warp (LACS WW)
You can wrong warp from Deku tree to the last part of the light arrow cutscene, turning you adult, skipping around 3 minutes of the cutscene. You can also keep farore's wind set from child to adult with this, though ideas to make use of that turned out to be slower. It has a long setup though, and means we can't use the Deku blue warp for another wrong warp, and can't use the light arrow cutscene for bottle adventure like in the old route. You still have to watch part of the the master sword cutscene later in the run, though the final part of first meeting sheik can still be skipped. Video: https://www.youtube.com/watch?v=t7eL6dBYu18
 
Text Transfer Glitch (TTG)
This glitch activates NPC events when they aren't supposed to be activated. It can be used for:
1. Selling bunny hood without having bunny hood. This skips even more of the mask quest than the old ass chest route did. Video: https://www.youtube.com/watch?v=JB2OeLYNzvM
2. Getting broken goron sword without poacher's saw (as child or adult). This skips getting poacher's saw on B like the old route. Video: https://www.youtube.com/watch?v=apxBfd1oJGQ

Fire Temple Zombie Jump
There's a new strat to jump to the top of fire temple, skipping almost the entire dungeon up to the hammer at the top, which is used in other categories like All Dungeons.  Even though 100% still needs to collect gold skulltulas through fire temple, it still ends up being faster to jump to the top first, and then go down the dungeon in reverse to collect the skulltulas.  Its awkward to fit into the run though since it requires dying, and the best place to put it is at the end, so we have to damage down 19 double defense hearts in shadow temple.

Zelda Escape Timer Wrong Warp
You can wrong warp from the cutscene where zelda escapes the castle to the nocturne cutscene by using a frozen timer from a trade item.  The timer expires at the same time the cutscene starts, causing the wrong warp, and skipping over 3 minutes of those cutscenes. This also has a complication where certain text boxes can reactivate the timer early unless they are closed frame perfectly.  There are 7 text boxes in a short section where not closing them frame perfectly essentially ends the run, and there's no reasonable backup.  This glitch is not new, but it wasn't in the previous route. It's been used in 100% before, though in a safer way that doesn't deal with frame perfect textboxes: https://youtu.be/ObwlHoNzXwk?t=8715
