Famicom Network Controller (HVC-051)

The Famicom Network Controller is essentially an overclocked Famicom controller with 16 extra buttons, which is pretty easy to implement, given that no emulator supports it. Reverse engineering work.

Thanks for the info @upintheairsheep. By any chance, do you have a rom that could be used to test support?
