Since I plan on doing more than just retropie on it at once, once you reboot it, it copies everything from the USB to the sd, that method still doesn’t work. So far no way to turn off the autocopy USB. So I’m just going to setup a symbolic link.
Also, in /etc/emulationstation/es_systems.cfg, I’m noticing that all/most of the systems are duplicated. Any idea why?
