Hey folks, so here's the deal:
Until now, whenever I beat the end boss in a Zelda game, the end credits roll and everything is reset to just before battling the last enemy, minus maybe arrows and so. But does something happen wif you completely finish a game? For instance, in my Ocarina of Time 3D, I need 9 more Skulltulas 3 more heart pieces and the golden scale and then I've done all there is to do. All sidequests, every upgrade, all 4 bottles. Everything. But if there's no big ceremony or change to the game, then I might not do it. Cause it's gotta be worth it, right? So please tell me, does anything change? Like do the 6 sages return to their natural habitats or something?
Thnx, Donavan

To my knowledge, and I have beaten the game before, there seems to be no change to the game after you have beaten everything, and gotten everything there is in the game. I am sorry if I degraded your expectations. But I do applaud you for trying to get everything!

well at first I didn't find the last skulltula I search everthing i find it is near of hyrule castle use a bomb in front near the village and voila there the skulltula I already collect of piece of hearts mini games sidequest before final boss sheik give link triforce of courage zelda appear from the disguise zelda kidnap by ganondorf after learned that link enter the temple of light and tells him meet him at ganon's castle if you want to save princess zelda cutscenes link shows the triforce of courage and zelda shows of triforce of wisdom while ganondorf plays piano tells them triforce is near here cutscenes ganondorf spits blood of him scream and destroys the castle nearly yet credits in nintendo 64 fire works show how you got everything sidequest skulltulas mini games collect rare items 3 arrows and you're done it you done everything.

Nothing Extra Happens to the ending to my knowledge.
If hackers were crafty they could do allot with this but I have yet to discover anything extra in any version of the N.64 Zelda O.O.T. game.
I have yet to go through the Master Quest or Ura versions of the thing but I doubt there will be anything extra in the endings for those either.

If I had the tools? I would install extra Story Content.
Extra action sequences with each of the characters.
Stills.
And New Music.
It is just a "credits roll."
Who would not want to alter it and muck around?

Good Luck.
Peace.

Thanks to all for the answers. TreasurePlanet23, my expectations aren't degraded. I really didn't believe there was goimg to be anyrhing different in the first place, but I just had to ask. Thank you for the applaud! Also, on master quest, I'm in the kingdom of far far away when it comes to absolute completion of the game. I'm not even tryin' there. For the longest time I couldn't care less about the big poes, because 3 bottles were more than enough for me. Honestly, I started the save file I'm talking about 2 years ago and just got all 10 poes yesterday anywho thanks again for the helpful info!

DiiTerryberry : No, there isn't.

As far as I know, the only Zelda game where side quest progress affects the endings is Majora's Mask, but only for the masks and Great Fairies.
