Unfortunately, I believe the answer is no. In game you need the keyboard to move through the menus, and with RSRBR to use the CamHack and Dll programs etc. It is a pain but.....................
If I'm wrong I would GLADLY hear from others is it would be easier if we could remap them.
I am working on making a switch panel right now that will take the place of the keyboard while I'm in RBR but I need either someone that can re-program a keyboard for me or I have to find a "mechanical" keyboard to run wires from to toggle switches and buttons on a panel mounted in my rig.
'f anyone can come up with a better system I'd love to hear them as i am struggling.
