As far as I know, this is just a LCD convention to insure that a game will
be fully visible on all TVs. It should be possible to extend your display
a few pixels below and above the conventional 2600 display. IMHO, most
TVs have more visible bandwidth available than they did 20 years ago.
The whole debate over 2600s generating closed captioning has to do with
writing to the overscan area, for instance.
