In the same vein as World -1 in the original Super Mario Bros., another “minus world” was recently discovered in The Legend of Zelda.
As part of a new series from YouTuber SKELUX, the player has vowed to uncover as many of these alternate glitched worlds hidden within NES titles, starting with Link’s first adventure. As seen in the video below, the user had to dig through the game’s code for over six hours to uncover the means of accessing the minus world.
SKELUX explained that The Legend of Zelda only uses half of the coded map, which makes it an 8×16 grid. Behind the scenes, though, he discovered that the map is actually 16×16, but the extra space cannot be accessed without tampering with the game’s code.
Once he cracked the code, the YouTuber discovered a strange version of Hyrule. Link can walk through several different obstacles, such as trees or rocks, and items are available in random spots. There are many graves throughout the extra spaces with a few ghosts wandering around. The player even stumbles across an Old Man that can be stabbed with the sword.
Unlike the minus world in Super Mario Bros., the new area isn’t accessible without hacking the game. However, for those that do take the time to break the code, the minus world is stable enough to play without crashes.
