Nintendo released the Famicom Disk System in Japan in 1986 as a floppy-disk add-on for the Family Computer, the Japanese version of the Nintendo Entertainment System. The format allowed larger games and save data, and early Disk System releases included The Legend of Zelda and Metroid. As emulation, retro collecting, and gaming history videos grew online, its startup sounds and chiptune cues became familiar shorthand for 1980s Nintendo. Creators still use this short clip to signal a Japanese release, a disk-era game, or a nostalgic return to Nintendo's early home console era.
