The Legend of Zelda: Ocarina of Time Master Quest

The Legend of Zelda: Ocarina of Time Master Quest is a reworked version of the original for the Nintendo 64. Master Quest contains largely the same content as the original Ocarina of Time, but with redesigned, more difficult dungeons akin to a Second Quest.

Master Quest was available on a special bonus disc that also contained the original Ocarina of Time. This disc was given out in limited quantities with preorders of. Additionally, it was sold packaged with The Wind Waker in some regions. It is also available as a mode in after first completing the regular game.

Changes from Ocarina of Time
The most notable feature of Master Quest is that every dungeon in the game has been modified to increase the difficulty of the game. Each one features a different layout, changing the progression through the levels. Enemies are spread differently throughout the dungeons, and tougher enemies are encountered much earlier on than in Ocarina of Time. In addition, some Gold Skulltula locations in dungeons have been moved, and certain items that are optional in the original version are now mandatory to complete the game.

Both games featured on the GameCube disc are displayed at quadruple the resolution of the Nintendo 64 version of Ocarina of Time, from 320 × 240 to 640 × 480, and the NTSC versions of the game supports progressive scan.

Ocarina of Time 3D Version
Master Quest for is not available from the start. To unlock it, the main quest has to be completed first. Upon doing so, the player will have an option to choose between the Main Quest or the Master Quest after starting up the game, allowing a second playthrough of the game with redesigned dungeons.

This version of the Master Quest has two significant changes. The entire game has been mirrored, similarly to Twilight Princess for the Wii, making Link right-handed as well as flipping the entire overworld map and the dungeons. In addition to the game being mirrored, all of the enemies and bosses will cause twice as much damage to Link, which also applies to the Master Quest 's own Boss Challenge version.

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 Ocarina of Time. Struggling to attract interest to the platform, Nintendo moved development of Ocarina of Time 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 Ocarina of Time, 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 Ocarina of Time. 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 ROM 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 The Wind Waker, a special bonus was offered for pre-ordering the game. This bonus is a Nintendo GameCube disc containing Ocarina of Time, 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.
