From the articles online, I had always thought that the airball proto had some kind of special hardware that made dumping very difficult. In fact, I remember someone saying that even dumped it wouldn't work without some extra hardware. Then I saw this picture at nintendoage:

If the board picture here is correct and I'm reading the chips right, I think anyone with a copynes could dump this without too much trouble. It also looks reproducible.

It would be really weird if this was NGD because this is the guy who bought NGD's dragon wars repro (see his recent feedback).

Do we know where both of the pictured protos are? There seem to be two different ones.
