I have a Pi 2 running retropie 2.6. I have limited space on my sd card so I was attempting to put everything on a separate USB drive. As I put the roms onto my usb drive, I tried to copy the folder tree on the pi so changing es_systems.cfg would be easy.
Once I inserted the USB and went to change the config file, it instead copied 1/3 of the files from the USB to the sd card. Any idea how to disable that feature?
