In my case I was trying it in VRChat, my remote let me move forwards-backwards-left-right but the Nunchuck was just rotating me I think.
So I couldn’t use the Nunchuck for gestures and things like you normally can with a touchpad as I understand it.
Let me know if I’m getting things wrong but that was my experience with generic bindings.
Also, would it be possible to use a Nunchuck just for gestures? I have two Wii Remotes and was thinking how easy it would be to tape one of my Nunchucks onto the side of one.
