GPD XD Plus Overlay Question

[drbabbers]

Does anyone know how on a GPD XD with Dolphin that I can hide the overlay but still use the GPD XD game pad controls? When I map using the GPD XD to the Dolphin overlay everything works fine, however as soon as I hide the layout my controls do not work. Probably more a GPD XD query, but wondered if anyone here has encountered the same thing and has any advice.
