Yes The Original Prototype (Blue Marquee) is Still owned by the Creator Rick Dyer, I had tried to prize this game from Rick for years, it is still in full working Order with its Original Wire Wrapped PCB, its stored in warehouse, The Early Demo DL had only a few Scenes, however there are a few collectors that Have the Proto Disc!! I have never heard about 2 way direction joy stick? Im almost sure this is not correct (My opinion)
