More than likely all these people with setups like this in their basements are OK (MAME, Jamma, or whatever). But, that thing is filled with licensed games, no way would I put that out in the wild set up to take money. Sure those games are old, but the IP owners are still out there and active. And Nintendo? They are seriously mean about stuff like this. I would not want to ever cross paths with them. And their lawyers.
