any racing games that use the wiimote held sideways are compatible with the wii wheel
Yes it does. The wheel itself does not control the game, you simply place the wiimote in it, and then it works as a wheel shaped controller. This makes it compatible with all Wii racing games, and there is around 50 Wii racing games to currently choose from.
you can use both but the wheel works much better
This is an opinion. The Wii wheel is more accurate on how much you turn, but is is very sensitive. I use the wii wheel.
No you can't and its wii u, not wii you.
Yes.
Wii sports active, Wii fit, Wii ski and surf are just a few of the games that use the Wii balance board.
Not hard at all.
can you use Nintendo Wii games in Xbox 360
Nintendo Gamecube games. That's about it
Wii U games cannot be played on the Wii.
You can only use Gamecube games and Wii games. If you want to use Gamecube games you need a Gamecube controller.
The wii is region-locked, you need US games.
