Ura Zelda (lost build of unfinished Nintendo 64DD game; existence unconfirmed; 2000)
Ura Zelda (裏ゼルダ in Japanese, translated as "Other Zelda") was an add-on to the N64 game The Legend of Zelda: Ocarina of Time for the short-lived Nintendo 64DD. The project was dropped due to the cancellation of the 64DD worldwide and the discontinuation of it in Japan.
Ura Zelda added many things to the original game, some of which may have been intended for the original release, but were cut due to time and memory constraints on the game. Some beta elements may have been intended to be re-added: the lost sword beam attack and the quest for the Triforce rather than the spiritual stones may have been intended to return. The fabled 'Unicorn fountain' however, claimed to be entered through Zora's domain, is often mistaken for being Ura footage while it was actually from early beta footage, and seems to have been an early design for the great fairy fountain (there is text supporting that the fountain would come to life, and the accompanying images show the early version of the Great Fairy in an identical room to the fountain; she is also the same color as the fountain). It also added things to the original game like improved cutscenes and graphics and an unused feature that saved things permanently, such as if a sign was broken it would not fix itself. Using a GameShark, it is possible to see a cutable bush that may have been planned for the Ura version in the existing game.
