So you’ve long since mastered Super Mario Bros. and it no longer challenges you? Have you tried playing it from right to left? That’s what Backwards Mario is all about. The first portion of the hack is getting the image to display backwards. He’s working with an old CRT television, which uses a magnetic ring to aim the electron gun at the screen. By swapping the left and right wires from that ring you can flip the image horizontally. Now Mario will be travelling right to left, but the controller buttons will send Mario the wrong direction on screen. This is a snap to fix, just crack open the controller and swap the signals for the left and right buttons. Now it’s time to fall in love with the classic game all over again, just like [JJ’s] doing in the video after the break.
