Ura Zelda (or Zelda Ura) is an add-on to The Legend of Zelda: Ocarina of Time (known as Zelda 64 at the time) for the Nintendo 64. The add-on was supposed to be released the Nintendo 64DD, but since the 64DD was not well-conceived, Ura Zelda was eventualy cancelled, and the game was arranged for a cartridge release. This is what we know as Ocarina of Time. Ura Zelda brought new content to the table, including 2 extra temples (Ice and Wind), 2 new tunics (white and yellow), new subquestsm including a subquest to beat the infamous Running Man, new characters, and many more things. These things would be available after you beat the game. 

The purpose of this petition is to get a bunch of signatures, show it to Nintendo, and try to convince Nintendo to revive Ura Zelda and remake it for the Nintendo 3DS.
