Neo Geo was SNK's cartridge-based arcade system, launched in 1990 and later released as a home console, built around powerful hardware and arcade-perfect ports of fighting and action games. The coin-insert chime became part of that arcade ritual, heard whenever a player paid to start a game in arcades around the world. As emulation, retro compilations, and gameplay videos kept those titles in circulation, the short sound survived as shorthand for old-school arcade play, and creators now reuse it to evoke that era instantly.
