Thank you!
Is there a way I can play with the CCP connected to the Wiimote?
Or do I have to get a USB controller?
Can I use a Madcatz X360 controller?
As long as the controller is hid compliant (i know official 360 pads arent but not sure about madcatz brand...) and has a controller.ini made for it, you are good to go.
The madcatz 360 controller MIGHT work (use hidtest to see if its compatible at all. if you press buttons and values change, it CAN BE DONE.) but, odds are you will have to make that controller.ini yourself (theres a how to bundled with hidtest) as I havent seen that floating around.
As far as the CCP, you have two options.
A) Buy a mayflash CCP to USB adapter (edit: IS still corded)

or
B) Wait for Nintendont to support bluetooth devices. It has been said it's in the works.
