It's true.  The NES light gun is a single bit optical sensor that must be
polled by software.

There's enough CPU time on the NES to monitor the light gun input in a
tight loop, get the exact vertical position, and also a coarse (+/- 10%)
horizontal position.  Duck Hunt (and other NES light gun games) didn't 
take advantage of that approach, though.
