Zanac is one of those space shooter games in which you are trying to save the earth, or something like that.
Due to the highly repetitive nature of this game, the author uses the hidden 9th input button (the console's Reset button) in order to warp to the last level. This results in an unsually long grey screen at the start of the movie as the author mashes 'Reset'.
Starting on the final level with only the initial pea-shooter for a weapon
normally makes the game impossible to win.
