Would be good if you could use a virtual mouse using the controller and maybe add a option button on the Pause Menu (when you press the Start button in game) saying `Virtual Mouse Off` and `Virtual Mouse On` when you press on it, to switch the controller from joystick to mouse and back, you need to be able to quicky switch between it so why it should be in the Pause Menu only.
Just a idea...
if it can do this already ignore this, but I did try and configured the controller as a mouse but it didn't work, the mouse pointer didn't move.
I suggested this because your able to do it in Retroarch by pressing the select button to switch between mouse and joystick, it works in PUAE.
