The whole screen flashes white for a frame, and you get a hit when the beam update hits the part of the screen that the gun is pointing at. ( If you have a light background you can sometimes get away without a flash ) Simply count cycles and scanlines to work out the position... On the VCS you'd be better of with the flash option - as you don't need to maintain a screen kernal for that frame - allowing better accuracy for the gun. Colin.

I thought that the gun games flashed a bright light from one small area of the screen, and if that light entered the lens of the gun a hit was scored. If the entire screen flashed white, I'm not real sure how the game could record the hit. Are you saying that the hit-or-miss event was recorded _before_ the flash, and the flash was a pause in which the game could process whether or not a hit was recorded? I suppose that would make sense as well. I've wondered about a light gun game for the 2600 before (what with Crossbow on the 7800, iirc), but seeing how far my platform game has come in the last, oh, two years?!?!, I haven't invested any time in making one yet... ;^) But that doesn't stop one from dreamin', eh?
