I recommend the non-pro classic controller if you want to use it for GameCube games on Wii (has adaptive trigger support).Go with a nintendo brand classic controller pro its nice to not always have to use the wiimote.
I had no idea, I had a backless Wii remote, then found a rechargeable back plate, then a charging dock.The rechargeable battery packs are better for your Wiimote (won't puke acid) and can be rebuilt using basic Ni-Cd AA's if they wear out. (Voultar has a video on doing this.)
Yeah it's called Nyko Kama.Wireless nunchuk? Those probably don't exist.
