I am having problems getting RetroArch to work for me. When I load it, I see a white screen with white letters (black outlining); in other words, the normal initial screen, but with the wrong colors. My controller (a Wii U Pro) is unable to provide any inputs. It is not frozen, however, as turning on another controller results in an on-screen notification that a controller has been added (the new controller also can't do anything). I have tried deleting the configuration file, but that does nothing. I am running CBHC, and RetroArch 1.6.0 Stable through the RetroArch channel/forwarder. I do not have a Gamepad connected to the Wii U at the moment, in case that makes a difference. Any thoughts on what the problem might be?
