Some box art not showing in Big Box

[Elvis Martini]

A few examples I can find:
Nintendo Entertainment System:
Batman: The Video Game
Bases Loaded II
Battletoads / Double Dragon

In 12.7, trying to view the artwork for these games in LB produced a crash, which was ticket #6665. The crash has stopped, but the box art for these games doesn’t show up in BB.

Artwork downloaded instead from EmuMovies does show up, but I’m getting a crash when attempting to download box art images from them for whole platforms.
