Most people don't know that the Wiimote communicates with the Wii via a Bluetooth wireless link. The Bluetooth controller is a Broadcom 2042 chip, which is designed to be used with devices which follow the Bluetooth Human Interface Device (HID) standard, such as keyboards and mice. The Bluetooth HID is directly based upon the USB HID standard, and much of the same documentation applies.
The Wiimote is capable of transmitting huge amounts of data to the Wii (Nintendo just isn't utilizing it's capabilities thus far). By using the internal Bluetooth wireless link, you can connect your Wiimote to your PC (any OS), and use it with a wide range of applications already made for the Wiimote.
So check out the next step and I will show you what you need to do.
Note: If any of you are having difficulties with this, just send me a message here. I'll be glad to answer any questions you may have.
Step 1: What you are going to need
Note, if you need a Bluetooth adapter, I recommend buying one here . That's the exact same one that I use, it's cheap and it comes with the BlueSoleil driver 184.108.40.206 on an installation disk.
If you don't have BlueSoleil already installed, you can download the latest BlueSoleil drivers from their website
Also, you're obviously going to need a Wiimote to connect to your computer!
