Reply To: no writing permission for retroarch.cfg

[jakko36]

Same happend to me with Mame4all-pi, i did not have permission to save the config to opt/retropie…… etc etc.
What i found was to do this in terminal: sudo chmod 777 (the map you need permission for) then go back mame4all-pi and you can map your buttons and save the config.
The same thing works with retroarch.
you will need root acces to cfg the most emulators.
