Anyone manage to get the right joystick to work in Aquila? I'm just wondering if there's a readily available option, as using left joy for movement and right joy for look would be excellent for my kid.

Similarly cannot get this to work. Probably your best bet would be to use an external controller emulator like x360ce/Xoutput/reWASD to map the joystick itself to input the arrow keys, then map those arrow keys as the right joystick, that is what I plan to TRY to do, though I have my doubts it will work like a normal stick.
