It came out nearly 40 years ago. They didn’t put out “real” motion sensing games until 2006. Feels like I’m missing something.

You can sort of see it if you look closely. It worked better on CRT TVs.
When you pull the trigger, the entire game screen renders black for a short period. Then the screen displays a white square over the areas that are a “hit” for a short period. Then the game continues displaying as normal.
The gun has a sensor inside that knows how long “a short period” is. So when you pull the trigger, the sensor checks if it sees all black, then it checks to see if it seems to be pointed at a white square. If it doesn’t see BOTH the black and the white square and they aren’t timed perfectly relative to the trigger being pulled, you missed. If it sees them both, you hit.
The reason for that quick black flash has to do with dealing with cheaters. Earlier versions of this tech skipped that part, and people figured out if you pointed the gun at a light bulb, you’d always “hit”. Since the NES gun checks for darkness THEN light, you’d have to somehow pull the trigger and be very good at precisely turning a light on and off.
This doesn’t work as well on LCD TVs because they don’t always change their pixels with the exact timings that CRTs did. Sometimes they do, sometimes they don’t.
