I was referring to the artwork on the armageddongames.com and zeldaclassic.com websites. A major part of the "other" repo is to avoid infringement of Nintendo copyrights and trademarks, especially in light of some pretty big lawsuits and numerous takedowns by Nintendo which are an existential threat to fangames everywhere.
Just recently, a whole website dedicated to fangames got shut down due to a DMCA notice. Nintendo has become highly litigious and not something that should be brushed off as nothing.
