In 1996, the gaming world was abuzz with excitement as Nintendo showcased their new console, the Nintendo 64 (N64), at E3 (Electronic Entertainment Expo). Among the games on display was a then-unnamed 3D platformer that would go on to revolutionize the genre: Super Mario 64. What few people knew at the time was that a special, exclusive ROM version of the game was created for attendees to play and provide feedback. This ROM, often referred to as the "E3 1996 ROM," was a unique build of the game that showcased its potential and gathered crucial feedback from industry professionals.
