Hah, that NFPMuzeum one does indeed have some good ones. I especially love #73, which proves once and for all that Indiana Jones was once the titular character from Princess Mononoke.
#101 is also great, because it's one of the few cases of cracked-out pirate cover art actually being at least as accurate, if not more accurate, to the game than the real art. Of course it'd be Samurai Zombie Nation where they pulled that off.
What the frak is Atachamanure School (#136)? The only hits I can find for that are listings of bootleg Famicom games. (Edit: Probably the Japanese-only game "Attack Animal Gakuen"...where "gakuen" means, of course, "school".)
Also, we finally have an answer as to what "Worldwide Publishing" actually is (#159)-- it's the "Tiny Toon 3" title hack of Crazy Castle! Of course. Not like anyone could ever guess that, though at least they chose a vaguely relevant picture.
