I've tried several tutorials, but none of them worked.
I'm trying to enable the GPIO controls to use an arcade control but I can not. Here's the procedure I'm running:
Via SSH I execute:
mount -o remount, -rw /
mount -o remount, -rw / boot
I make the change in the file recalbox.conf
I run the command /recalbox/scripts/recalbox-save-overlay.sh
Restart the Raspberry Pi3 Model B and the setting is not applied.
I have already tried to delete the / boot / boot / overlay file and it did not work.
Would you help me? I do not know what else to do.
