I want to know the answer to the following question:
Who attached a Game & Watch D-pad to the Famicom prototype?
All the background I'm provided with is that "The game pad controllers were more-or-less copied directly from the Game & Watch machines, although the Famicom design team originally wanted to use arcade-style joysticks, even taking apart ones from American game consoles to see how they worked.". Is that enough to answer the question?
Answer: no
