I just tested it again, with a few different systems, It does kind of squish the box, especially segacd, maybe a 640x640 square would be better. I'm sorry I'm not very good at this artwork.xml, I cant find a way around skyscrapers, compositing the boxart, even though all that it needs is for "cover" to be redirected to "screenshot". Did you try the built-in scraper?
