Anyone got a help on this one? I tried adding the joypad config from the /all folder to the individual NES config folder, and changing the retroarch file in the NES to include a line of redirect (found it on reddit). It recommended switching in the cfg file the config that was backwards. I tried that and then NONE of the buttons worked in NES.
Changed things back and am back to 1 … UP and DOWN still reversed from normal config.
