Zelda 64 Dawn & Dusk is a ROM hack from The Legend of Zelda: Ocarina of Time that was created by Captain Seedy-Eye for the Nintendo 64DD. All maps, music and dungeons are custom made.
This game presents the conclusion of a past war between two halves of the same kingdom, the East Dawnside and the West Duskside. This has been patched to work on an N64. It requires the Red RAM Expansion pack to work.
