It's not quite a historical event, more of a bit of trivia, but it seems to be common knowledge that it's possible to cheat at Duck Hunt by pointing the light gun at a light bulb, making it register a hit every time, often repeated as a sort of "look how far we've come, those silly game devs in the 80s missing such an obvious exploit."
Except it doesn't work. The light gun checks for a frame of darkness followed by a frame of light. If it picks up light when it's not supposed to, it counts it as a miss because it knows what you're pointing at isn't the screen at all. But people in all corners of the internet are absolutely convinced this trick was a thing for some reason.
Some recent cheap, pelt poorly regulated LED lights flicker on and off at high speeds.
Would it work with these?
Well actually pwm is used in everything except really expensive lights. Also if you timed it perfectly maybe?
Oh I mean awful lights like your get from AliExpress where they’ve essentially just rectified the circuit but not bothered with caps so it’s flickering at 50/60Hz.
Ohh yeah. I think thats even better for cheating prob because the frequency is lower but i dont know how the game functions exactly so maybe its harder to cheat.
At best, if it flickers at exactly the same as the framerate (60Hz NTSC or 50Hz PAL), you'll have a 50% chance. Either you pull the trigger on a light "frame" or a dark one, and it's followed by the opposite. You can do better than 50% playing normally.
Because the Angry videogame nerd showed it works in one of his videos, that's why
