I hoard metadata in a frontend for games called EmulationStationDE. Since I think it's cool to see what different platforms had + see box art, gameplay video, yatta with scraping.
Been playing with their 2.0 beta releases and themes + editing some of them myself.
This one in particular has a cool aesthetic.
What the guy did with the theme I recreated with a few platforms is if there isn't a sprite, taking stock photos and shrinking them down then overlaying scanlines on top. lol Lazy but it's hard to discern the difference.
