I have an retroPi img file that I wanted to view the contents for. I've burned the contents onto an SD card and when my Mac mounts the volume, I only see 50 or so megabytes worth of content, yet when I boot it up in the Raspberry Pi, I can play gigs and gigs worth of roms.
Where is all this content hidden? Is there any way to view the contents of the IMG file properly? How does this all work?
