Finally sorted it for now.found it on another web site.You have to turn the wii remote upside down and hit it onto the plam off your hand a couple of times quite hard.And hay presto it turned around the right way
I totally wiped the wii back to factory settings and then reinstalled homebrew and it still does the same.Also swapped the wii from top to bottom,And done the shakey thing still teh same
My homebrew channel was working fine but my cursor has now has gone inverted and upside down.You have to hold the controller upside down to use it.Real weird.I have uninstalled the channel and then reinstalled still doing the same any suggestions?
