Sega launched the Dreamcast in Japan in 1998 and the rest of the world in 1999, and asked renowned Japanese composer Ryuichi Sakamoto to create its startup sound. The eight-second chime played every time the console switched on, and as the Dreamcast became a cult favourite despite its short commercial life, the sound turned into a symbol of late-90s gaming optimism. Today it sits alongside other era-defining system audio like the Windows XP error music in retro compilations, console startup rankings and vaporwave-style nostalgia edits.
