I have Super Mario Galaxy 2 in the Dolphin Emulator. Since I have to point for certain things and use the joystick on the nunchuck for general movement (and I don't have a USB sensor bar), I want to play with the nunchuck in my left hand and the computer mouse in my right hand, while the Wiimote just lies around (because I don't have a third hand).
I've set mouse up/down/left/right to move my cursor in the game up/down/left/right (I don't remember the name of the setting right now) and that works fine, except that it only does so sometimes. The in-game cursor appears and disappears seemingly randomly, sometimes for a second, sometimes for 10 minutes, sometimes until I restart the emulation or change the configuration of the controller and change it back.
How can I make the cursor reliable?
