I’ve just finished a Super Nintendo set. This caused a few problems as I couldn’t find a source of every cover, I have a virtually complete USA set but not much from other regions. Where possible I used the USA for all regions but there were still lots missing (particularly Japanese games) so for those games I created fake covers using the title screen as the cover art. It’s not perfect but it means that every game has a 3d box.
I’ll link all of the preview packs so far below so that they are easily visible (I can’t edit the first post for some reason otherwise I’d put the links there.)
