This is a development cartridge containing a retail build of F-Zero X, however what makes this cartridge special is that it contained an overdump for a very early version of The Legend of Zelda: Ocarina of Time from around the time of Nintendo’s SpaceWorld 1997 tradeshow. The data for Ocarina of Time contains maps, textures and text, were are all fully intact. Unfortunately, all character models, code, and audio were overwritten by F-Zero X. This cartridge was acquired from a former Nintendo employee.

Zelda 64 data begins at 0x1000000 in hex.
