Forest of Illusion, a Twitter user who collects and hosts information about beta builds of video games, has accidentally made a new discovery involving a classic Zelda game. After dissecting a prototype cartridge of F-Zero X, they found that the ROM dump contained a few files from an early build of Ocarina of Time. Supposedly, the files are dated to around the same time as Spaceworld 1997. The information that was pulled from the dev cart consists of beta map data for the game, along with early textures and graphics files. Following this discovery, some users began porting the maps into Ocarina of Time, letting players experience these areas in full, such as a beta version of Kakariko Village, which can be seen in the above video.
