The Legend of Zelda: Ocarina of Time Master Quest

Originally released as a bonus disk for those who pre-ordered The Legend of Zelda: Wind Waker, The Legend of Zelda: Ocarina of Time / Master Quest contains GCN versions of Ocarina of Time and the never-released 64DD title Ura Zelda, a remixed version of Ocarina of Time with harder dungeons. These emulated versions of the N64 games have several technical improvements over the original N64 versions, such as 640x480 resolution, Dolby Pro-Logic surround sound support, and 480p Progressive Scan support.

Problems
The game may crash if a wall or other non-damage-able object is hit with a sword.
