Alright so my new Razer Kishi finally arrived.

Basically it is a clamp that fits on the left and right side of your cellphone. And it does work with Pico-8 from Firefox, sort of. The arrow keys are the rolling joystick at the top, which is not what I want. I want it to work with the arrow keys beneath that.

Is there some way I can remap these keys in Pico-8 from Firefox so they use the standard 4-way arrows ?
