3. Save and load up pkmn-chest
4. Load Emerald save and switch to the box(es) with the custom wallpaper
5. See error

Oh, looks like I missed them since they're listed separately on bulbapedia. https://bulbapedia.bulbagarden.net/wiki/Wallpaper#Walda

Probably just need to add the image files and it should be good, I'll do that in a bit.
