This is pretty interesting, wire a controller to play and beat two SNES games at the same time – “One person’s silly idea is another person’s inspiration. This movie is essentially constructed by taking one controller and wiring it into two SNES emulators at once. The same input is used to play both games to completion. In other words, the player plays two games simultaneously with one controller.” [via] – Link.
