The Legend of Zelda: Ocarina of Time" came out on the Nintendo 64 to much acclaim. Nintendo then created an alternate version of the game called "The Legend of Zelda: Ocarina of Time Master Quest" that had the same quest but the dungeons and puzzles were changed. This was originally intended to be released on the Nintendo 64dd a disk drive attachment for the Nintendo 64. But due to poor sales of the disk drive, the game was stuck deep into Nintendo's vault instead of being released.
The Legend of Zelda: The Windwaker on the Nintendo Gamecube, they decided to release a bonus disk containing both The Legend of Zelda Ocarina of Time and Master Quest. Finally, fans were able to play the Zelda game they had been missing.
