Being able to play NES and SNES games on the Wii's Virtual Console is great (Thanks Nintendo!), but it's much more fun to do it with the original controllers. (And some games are much more playable like this).

This circuit makes it possible to use a NES or SNES controller on your Wii or Gamecube. No microcontroller programming or surface mount component soldering required. All you need to do is to solder the gamecube and nes/snes/n64 controller wires. The circuit is small enough to fit in an original controller!

  • Compatible with the Game Boy Player and emulators.
  • Compatible with the Switch (combined with a Nintendo Gamecube adapter for Wii U). Firmware v2.2 or newer required.
