Custom GPIO controller

[sitmar]

Hi guys!
I am making my own handheld recalbox. I would like to use GPIO controller and GPIO display. But display and controller pins interfere with each other so this is a problem. I am considering using PAL screen and standard GPIO controls, but PAL screen needs 12V power supply.. So my question is can I somehow remap GPIO pins for controller? I've already searched the internet but could not find the answer..
