@cwalk828 Usually this is up to the theme, the scraper just downloads the files (images/videos) and adds them to the gamelist.xml used by Emulationstation. But I don't think this is supported by Emulationstation (playing video in the bg) - if you're interested in this kind of display I think Pegasus (another front-end) might support this.
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?
Box Art is not included in the ROMs, so it must be downloaded separately. You can use a 'scraper' program to do that, there are 2 included with RetroPie - https://retropie.org.uk/docs/Scraper/ - but you can try others as well
Just a suggestion for the devs: it would be cool if we could manually scroll the game description with the right analog stick, and if the stick isn't touched or the controller doesn't have one it would scroll by itself (adjusting the autoscroll time would be cool as mentioned above)
@valhalla_pi I couldn't find it at first but I found the lines were there in carbon.xml, not in theme.xml.
Like you said, I only had to change the showSnapshotDelay into true and add the extra delay line. Works!
