I spent some time thinking about this problem a while ago, and I think I have a solution that I would never actually take the time to implement. The trick would be doing it all fast enough, which is over my head. * Intercept the video output from the NES. * Place a camera on the end of the zapper. * Use static images such as the trees to determine the coordinates of where the camera is currently pointing. * Use LEDs directly in front of the zapper's sensor adjust the light to what those coordinates would be based on the intercepted output of the NES.
