Can you post a schematic? and would you be happy to use a joystick if it were provided free?

It seems unlikely, but sometimes things happen just for asking.
I got to use our government's topographic maps in an iPhone App, and in another App,
I got to legally use a system ROM of the Commodore Amiga for an emulation, and that's just in 2013.
Some things like that seem like it wouldn't happen, but sometimes it's not the case.

Knowing what the rules are, even though I don't like them, I would opt for Space Invaders.
