Okay thank you guys
Found out that you have to have 2 usbs
1 with a “retropie” folder
Thus will auto copy games from usb to sd card and then unmount itself
And the 2nd to play ur roms from
After config of the rom diectory you can set it to the appropriate directory for the roms you want.
You will still want to save the “roms” folder to this usb but u just need to have it edited in “es_emulator.csg”(dont quote me on that file it sounded like to righr file).
