I’m running it using the retrorama theme. I’ve worked out the boxart issue by creating my own Named_Boxarts folder in specific systems folder in Thumbnails folder. There was only a couple that didn’t have them. Atari Lynx and Atari 8 bit. As you scroll along the top in landscape view Retrorama shows, in mine for example, Atari 2600, Atari 5200, Atari 7800 the Atari Lynx and then Atari-8-bit. Both these last two are just called Retrorama Video Game System instead of the Atari names. Hope that’s explained well enough.
