Today, I was thinking about getting the triforce before hyrule 1 or 2. MAY be possible in TAS, doubt it though. Anyways, its hand interesting results.
Getting the Triforce before hyrule 1, but after raising ToG, and then completing ff2 is strange. Hyrule 2 turns into a hybrid of all 3 hyrules. The colors are gone still. The triforce blocks need to be pushed. When you enter the chamber, Zelda is standing infront of Master Sword. The MS isn't drawn, like Hyrule 1 skip usually is. Zelda infront of the sword is the Hyrule 3 cutscene. When you approach, she disappears and the 2 darknut fight happens. They are both gray. After ending the fight, the fire disappears. When you leave, you instantly fadeout and the Hyrule 2 cutscene where Tetra becomes Zelda is loaded. You appear in the chamber next to Tetra, but you can move and no cutscene occurs. You can walk right through her. Leaving goes into normal Hyrule and the barrier is not breakable. After leaving and trying to complete ToG, I crashed after finishing the boss and the quick cutscene afterwards. I didn't get to ring the bell.
Here's something even more fun, a dead-end. Complete Hyrule 1, then get the Triforce, then go to Hyrule 2. The cutscene of you talking with Tetra won't occur. Tetra won't appear. KoRL won't talk. You can get in and leave. Inside, the chamber is closed. The electric barrier is blocking the way to the barrier. There is no way to open the chamber. If you leave on KoRL, he won't talk. You won't even be able to talk to him later. The sea chart doesn't show where to go. You can't get Fire and Ice arrows. Good game.http://www.youtube.com/watch?v=3CVzmB-rruQComplete Hyrule 1, get Triforce, then go to Hyrule 2. Strange effects. Pretty much, the statue is in place on top of the chamber. In order to get into the chamber, you need to clip under the castle (Using Mugg's method for the Hyrule 1 fight skip). Entering the chamber activates the Hyrule 3 Zelda Cutscene/fight. When you leave the chamber, the Hyrule 2 cutscene loads, but doesn't play. You are standing infront of the Master Sword pedestal and Tetra is standing next to you, and she has no collision. Leaving now works, the statue is still in place. You can walk right through it. If you go to the barrier, the electric barrier blocking you from it disappears. Klydestorm said that that is one of the requirements for being able to brake the barrier. Sadly, since you don't have the MS3, you can't break the barrier. At this point, leaving causes the KoRL to give the Hyrule 2 text. If you talk with him again, he gives the text after the Hyrule 3 fight telling you to go to Ganon. Seems like no skip here yet. The temples are shown as places to go on the Sea Chart.
