I do think a lawsuit for showing what's inside is a bit toothless and silly. Emulators have basically replicated the "guts" of various game systems and legally there is nothing Nintendo can do. But you just can't legally copy actual games. So selling knock offs you can't do, and you can't violate trademarks and stuff, but if I can open a big Mac and show what's inside, then pretty sure I can do it with a boxing glove.
Full of himself for sure, but I actually love him as a "character" in his field. No doubts about the passion there. A bit nuts maybe, but isn't that true about about most great artists?
