You don't need the Zora Tunic to complete OoT, You don't need the Goron Bracelt either, The Uber challenge requires the use of numerous glitches, and most are harder to pull off than completing the game itself.

I completed uber challenge, when it first came out, a very difficult challenge for even the god-like players of Zelda, but very awarding, i recommend you all give it a try.
