I suppose that would make sense as well. It looks for the _position_ of the gun (not for a hit of any particular duck) during the white frame.. when the light gun sees the electron beam (emitting bright white), it tells the NES so, and the NES makes a note of where it is on which scanline, which is the position of the gun. _Then_, it compares the position of the gun with the coordinates for ducks and other objects. The whole system does a very good job of fooling the user into thinking the light gun is able to see and detect ducks, but in reality it's nothing of the sort. -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
