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.
