An extension for The Legend of Zelda: Ocarina of Time originally known as URA Zelda was originally going to be released by Nintendo before it was ultimately cancelled. It may have been cancelled because it was planned to be released for the N64 Disc Drive, which was released late in the console's lifecycle and undersold in most markets. What was known, however, was that it would have added new features to the game, such as Link's footsteps appearing in sand, having damaged trees, having bushes and grass damaged for the entire game, and changing up dungeons.

In 2012, a Youtuber named ZethN64 said he was going to try and recreate URA Zelda. He and his team wanted to make their own new dungeons, story, and soundtrack for the game. It was unfortunately cancelled, as there were conflicts within the team as well as ZethN64 disappearing.
