How are you editing your .cfg file, in linux, windows or WinSCP? If the edit is a paste from example a forum as this in windows the format and fonts could make it weird in linux (RetroPie). Try editing the file from the terminal or via SSH, remove and or re-add the (“) character and do a backspace on all ” ” whitespace eg. (input_overlay=) to (input_overlay =) again. Im thinking this could be the problem since when RA is writing the value it’s working (linux environment).
