@mitu This help request can be closed out. I ended up uninstalling retropie and Ubuntu and put Batocera on my SSD. Batocera seems to be more user friendly in terms of initial installation and settings. From what I've read Retropie has more options/settings but my emulation needs are simple and Batocera serves me well.
