Street Fighter II launched in arcades in 1991 and made Capcom's head-to-head fighter the template for an entire genre, with the versus screen becoming a ritual: two portraits, a staredown, then the fight. Its sounds passed into gaming culture as shorthand for any showdown, sampled across edits, streams, and remix videos for decades. This particular blip survives because it is pure function — a split-second of retro arcade hardware that tells any viewer a contest is about to begin.
