First of all, i would like to thank you all for this amazing project !
I’m currently using a 1Tb flash usb drive to store and try to keep a clean installation folder (which is just a small 2Gb micro sd). I much prefer this way in order to keep Retropie standalone (and i tend to mess around a lot).
I moved all the roms back to the usb stick but I can’t find the proper way for the scraper to store gamelist & downloaded images (most important folder which takes a lot of space) directly on the usb.
Right now, i just managed to change to mass edit the directory inside the gamelists but a better way would be to tell the ES python parser to put and retrieve images inside /media/usb0/Emulation/downloaded_images/xxx.
