how to download roms onto raspberry pi 3/recalbox

Without any network access it's pretty hard. Can't you just plug a wifi adaptator ? (just to transfert Rom) meanwil, you can try with an USB Key. The roms are in this rep : /recalbox/share/roms But, I don't know where are the directory for scrap (xml and images) but you can put them directly in the rom directory.
