Played on an original NES, cart, and Zapper

Attempt session:

Video was recorded in 30FPS and framecounted to 2:50.800 with first frame, where noninterlacing 100k is visible, which is at least one frame too late, since middle of the screen textbox is also visible, which appears one frame after updated score in lower right corner. If we take interlacing frame as last one , then final result would be 2:50.767. However, we also see at the beginnig of the run, interlacing "round 1" textbox in the middle without dog on the screen. That textbox without dog is visibile only for 1 frame in 60FPS before dog appears, thus using that reference point , first visible dark screen frame , when run starts, is one frame too late in reality. That makes most probable time of this run: 7:50.783 /hirexen
