so in pi@raspberrypi ~$ i type /home/pi/RetroPie/configs/all/retroarch.cfg and ENTER to see if it exists and after in the file i type:

# cp /home/pi/RetroPie-Setup/supplementary/settings.xml /home/pi/supplementary/supplementary/ES-config/

and save and after try the controll ?

But what do i do if that file not exist ? :S
