The A button confirm tone comes from the Pokemon role-playing games released by Nintendo for its handheld consoles, where the A button has long been used to talk, select and confirm. As gameplay clips, remixes and memes moved online, players ripped and reused the familiar interface sounds from their favourite series, much like the Mario Jump effect. Because the tone is so short and recognisable, it survived changes in hardware and graphics, remaining a shorthand for a confirmed choice in fan videos, streams and edits today.
