This game was shipped together with a special edition of Legend of Zelda: The Wind Waker in May 2003. It basically contains the whole storyline of Legend of Zelda: Ocarina of Time, but includes altered dungeon layouts and more powerful enemies. The alterations concerning the dungeon maps contain the addition of other/stronger enemies in several rooms and slightly different room layouts (items are placed on different locations, and puzzles have to be solved in another manner). The game was originally developed as an 64DD add-on cart for the Nintendo 64 version of Ocarina of Time code-named Ura Zelda.
