while I'm not sure of the midget market, this brings up a question...  I know that ROM and MAME distribution are illegal, but would it be illegal to make and resell machines with a Jakks hack?  I mean, we might be able to tell the difference, but how many "average" people could?  I know I certainly couldn't make a profit out of it, but it might be worth a shot once.  I'll do anything one time...  LOL!
I don't think this would be illegal, but curious about the forum's thoughts.
**edit** Forgot about monitor orientation.  That could be a killer.
