Yeah, this confused me for a while as well, but here’s what you need to do.
What you need to do is take the output of /home/pi/RetroPie/emulators/RetroArch/tools/retroarch-joyconfig and add it to the end of /home/pi/RetroPie/configs/all/retroarch.cfg

Just pipe the output of retroarch-joyconfig into a file and append that file to the end of retroarch.cfg

That should do it.
