Just today I bought this Wii extension controller with the intent of using it on my PC, since the box says that a USB port is used for the wireless emitter.


Unfortunately that wasn't the case; the wireless emitter only has one port that apparently only connects to a Wiimote (which I don't own). Is there a way of connecting this controller to a computer? Maybe a adapter between the extension port and a USB one?

I've tried to see if it uses Bluetooth, I don't think it does.

  • I'm going to go on a limb here and say it probably won't work. If it's wireless, it's probably going to be some kind of proprietary signal, and it's going to link up to a Wii controller which passes on the commands. Sorry. If it uses Bluetooth, you might be able to use GlovePIE, but it's going to be harder than usual without an actual Wii controller.

  • @Arda - you can connect a Wii Remote to a PC via Bluetooth. It's a standard Bluetooth device with nothing special to tie it to the Wii.

  • @ChrisF I know, but this device is meant to be connected to a Wii Remote, not directly to the Wii. What I believe the OP is trying to do is connect it up without a Wiimote.

The Wii controller extension port uses an I²C connection with a proprietary but simple protocol. Many people have reverse engineered it and used the controllers in electronics projects, and according-to-Google there is at least one commercial product, by “Mayflash”, that adapts Classic Controllers (i.e. what you have) to being standard USB HID devices.


You could buy this adapter if your remote came with a reciever to plug into the wiimote. It is used to connect a normal wii classic controller to a pc, so as long as your remote has something that is supposed to plug into the wiimote, this should work for you.
