Mega Man X launched for the Super Nintendo in 1993 as Capcom's darker spin-off of the classic Mega Man series, starring X and Zero against Sigma's Mavericks. Setsuo Yamamoto's stage clear theme became one of its most memorable motifs, replayed at the end of every boss stage. As retro gaming clips, emulators and speedruns spread online, fans ripped the jingle for videos and soundboards. Its short, triumphant shape makes it perfect shorthand for mission complete, which is why creators still use it decades after the original release.
