Roms are in
When I remote access the Pi from my Mac I get option to view three different folders:
In the same-mame4all Config folder I see
and a folder labeled “cfg” inside of which are “.cfg” files for each of the games I have in the corresponding Roms folder.
I can open these files in Textedit on the mac, but the only one that seems sensible so far is the mame.cfg file, see screenshot attached.
