This is the Legend of Zelda Ocarina of time Master Quest ported to 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.

Experience different puzzles, monsters, and chest item locations. Dungeons are completely redesigned and challenging.

There are two versions of this to choose from. Regular and Debug. The regular version is just the game how it would normally be played. There is also the Debug version. This version you can choose save file 1 to manually choose from a list of areas to explore. Save file 2 & 3 are the normal game. Also button presses are dispalyed in the lower right corner on this.
