And I didn't get around to make the aforementioned changes for your setup either, because I'm on vacation for a movie festival where I watch 2-3 movies every day over the whole week. :)
About the artwork's space: Yeah, I figured as much. But none said that retrogaming is a piece of cake (and if they said that, they lied). I'll keep this on my to-do list and look forward for any updates on your side.
