what do you use to enter your pi?

i use winscp and cyberduck….
i log into the pi with root permissions.

when you put your sdcard into a windows pc you are only able to change the boot.cfg and some other files and yes indeed the /opt/retropie/configs/all/ does not show up. Use “winscp” or “cyberduck” to log into your pi and change any .cfg files…
