Mega Cooperator (2016)

A custom controller built for Sega Genesis/Mega Drive consoles. It plugs into the console's controller port and mimics the actions of four buttons.

One button is randomly assigned to each of the four players. Every 30 seconds the actions switch around, so players need to communicate to figure out who has what, and to operate the game.

An attempt to use the device to complete the entirety of Sonic the Hedgehog 2 was filmed in early 2017.
