Rockman X4 was released by Capcom in 1997 for PlayStation and Sega Saturn as the fourth entry in the Mega Man X series, known as Rockman X in Japan. Its menus used short electronic cues for moving and confirming selections, sounds that became familiar through repeated play between stages. As gameplay clips and soundboards spread online, fans isolated the confirm cue for edits and streams. It remains popular because it is instantly tied to 1990s Capcom presentation and signals a choice clearly without dialogue or music.
