History
In the late 1990s, Nintendo developed an add-on peripheral for the Nintendo 64 called the Nintendo 64DD. The Nintendo 64DD used magnetic disks, with a larger memory capacity than the cartridges used for the Nintendo 64, allowing for additional content and improved models and textures. While Nintendo hoped that the Nintendo 64DD would attract third-party developers, they also began developing several first-party titles, one of which was. Struggling to attract interest to the platform, Nintendo moved development of to the Nintendo 64, which was ultimately released on a cartridge. At the time of this change, the game featured more content than the cartridges could hold and so parts of the game had to be removed.

Ura Zelda
Shigeru Miyamoto announced that an expansion would follow, tentatively known as Ura Zelda. The expansion was purpoted to include rearranged dungeons from the original game. The Nintendo 64DD became a commercial failure in Japan, and so most of Nintendo's planned titles for the 64DD, including Ura Zelda, were never released. Miyamoto insisted that the game would continue to be developed, and in August 2000 indicated that Ura Zelda had been completed for some time. Despite this, Nintendo could not decide on how to release the game, and considered different methods such as a magazine tie-in.

Remnants of Ura Zelda's 64DD origins still remain in. Several error messages exist in the game's data regarding wrong disks being inserted. A "Disk" tag can also be made to appear in the title screen by modifying the RAM addresses of the game. A save file can also be flagged as a "Disk" save and a "Disk" icon will appear next to the save file on the file select screen. The file will be permanently grayed out and inaccessible, unless the game is tricked into thinking the expansion disk is inserted. Attempting to open the file afterwards will crash the game, presumably due to the game trying to load non-existent files.

Master Quest
With the release of, a special bonus was offered for pre-ordering the game. This bonus is a Nintendo GameCube disc containing, as well as a release of Ura Zelda, titled outside of Japan as The Legend of Zelda: Ocarina of Time Master Quest. Master Quest contains altered dungeons with a steeper difficulty level, as originally promised for Ura Zelda. Both games on the disc are emulations of Nintendo 64 ROMs, and not direct ports to the system. A modified version of Master Quest is included with for the Nintendo 3DS, but must be unlocked by completing the regular game first. As well as all changes from Master Quest on the Gamecube, enemy damage is doubled, and the game world is horizontaly flipped.
