SmashWiki:Protected image list/Extracted files
There are certain kinds of images on SmashWiki that have no valid reason to be changed. Extracted files cannot possibly be improved unless a later game update changes them.
Technically these aren't all extracted, since Sheik isn't selectable in Melee and SSB64 doesn't have images for this sort of thing. But the rest are, and they have no reason to be changed anyway.
