I was able to successfully set up my controllers, and NES, Genesis, and Gameboy I get the tale tell sign retroarch is working because I get the yellow text at the bottom prior to the emulator booting. However, I am not seeing this yellow text with PiSNES or SNES9X.
PiSNES – Controls are incorrect, X and Y are A and B, Start and Select do not function and shoulder buttons are correctl
Snes9X – Controls are mapped appropriately, but do not use RetroArch configuration, so the two button press restart does not work.
GBA – Controls are mapped but again, no ability to use the two button exit.
