Before the advent of wireless controllers video game consoles were built like tanks to survive the countless times they'd be inevitably yanked to the ground when someone tripped over a cable. If only the wireless technology needed for this hack existed 20 years ago.
The mod isn't for the hacking feint of heart. You'll need to do a lot of fitting, wiring, and soldering work on a Super Nintendo controller to get all the components squeezed inside. Including the addition of a power switch, emitter and an LED power indicator. But the effort is totally worth it for the handful of peoeple who still keep a functioning SNES hooked up to a TV instead of using the Virtual Console on the Wii.
