Super Mario World launched with the Super Nintendo in 1990 in Japan, with the overworld theme composed by Nintendo's Koji Kondo. The tune became one of the most recognisable melodies in gaming as the console sold tens of millions of units. It spread further through YouTube remixes, speedrun streams and retro compilations, where creators lean on it as shorthand for 16-bit nostalgia. Decades later it still signals cheerful classic platforming in edits and memes.
