Welcome to my Triforce rumours section.  Everyone is trying to break the biggest secret in all Hyrule, how to get the Triforce.  In this section will find the latest rumours and gossip on how to find the Triforce.  Probably most of the rumours are false but if we keep searching sooner or later we'll find it.

           Well here it is First of all  you have to have already beaten the game and viewed the ended. This next part is a  little tricky but of course a secret like this isn't going to be easy! It dosnt matter if you've
  died already but you do have to have all 100 skulltullas (a reward a little more satisfying than that gold rupee huh). You don't have to have all the heart pieces either. First blow all the gossip stones into space using the bombs. You must keep track with which ones you've already shot off because they reappear (note: leave the 4 stones infront of the temple of time because you can't bomb them). Once this long feat is completed go to Link's house.  Now play the song of time anywhere in his house ( you won't hear any noise but trust me it's working). Now go to Lon Lon Ranch and stand infront of Malon. Again play the song of time. Now play the same song once more any where inside the windmill in Kakorika village. Now this next part really suprised me. OK now return to links house and guess who will be waiting for you ...dark link.he will be sitting on the center table.  He won't talk to you until you play sarias song, then after a short conversation he will teach you a very important song "the song of the sages"(you must remember it because it won't appear on the quest status menu) which will warp you to the sacred realm (this song will not work anywhere except in front of the 3 spiritual stones. There will be a platform there, so it is sort of obvious where to play the song). At your arrival at the sacred realm you will find that all of the sages have been trapped in a large cage by Ganon. They tell you that the only way to set them free, save hyrule, and obtain the entire triforce is to defeat Ganon again. They combined their power to form another rainbow bridge leading down to a door.  Inside you will see the triforce. ( It is not the same as your screenshot) if you walk towards the triforce, a green sphere will appear around it. ganon will fall from the ceiling and the
  fight will start. He will suck all of your weapons and shields and you will have to use the kid sword. It took me 52or 53 tries to finally defeat him.  As soon as he is dead, the sphere around the triforce sappears. Hyrules returns to normal, the sages are rescused, and Zelda becomes ruler of Hyrule and most important the triforce is yours (and it does show up on your quest status sheet).

my opinion and facts
       I've tried this out but I can't get it to work, if anyone finds that this does work please tell me but so far I think it's just a hoax.
