I am having trouble figuring out how to load ROMs onto Retrosmc. I managed to get Retrosmc itself installed after some difficulty (had memory issues while installing but figured out a fix thanks to this thread) but now can't get the games where they need to be. I saw a post advising this:
"Copy roms to /home/osmc/RetroPie/roms/systemname/ to make the emulatormenues appear."
But being new to this game, I don't actually know how to copy files from my desktop to this directory. Does anyone have any step-by-step advice for accomplishing this? Thanks so much. I should mention I am using a terminal in mac to SSH my way around the osmc.
