Dolphin, the GameCube and Wii emulator - Forums

The new plugin is working really great except that I need to map the A/B buttons as L/R mouse click respectively, is it possible to do this ?

Yes.
I'm assuming you are using a gamepad for the rest of the inputs...?
Right-click the button for A in the wiimote config, choose the mouse device in the device list on top, manually select "Button 0" in the input list(or use the detect button), click "Select".
Do the same for button B, but set it to Button 1.

It worked, thanks!

And yes my Gamepad handles the rest of the buttons.
