The reveal comes from X user @ChrisMack32, who posted a video showing them unplugging a Super Nintendo controller – connected via USB – at one of the Nintendo Museum’s booths. Removing the cable from the controller results in what sounds like the familiar noise that plays when a Windows device is disconnected. If you listen carefully, you can also hear the Windows ‘device connect’ sound when the controller is plugged back in.
Even earlier with Pokemon Stadium’s Gameboy emulator.
