Using a Wiimote as a position sensor, a raspberry pi, an arduino, and an LED, someone has "solved" the Zapper + Modern LCD issue:

[Charlie] has attacked this problem with some more recent technology and a bit of lateral thinking, and has successfully brought light gun games back to life. He senses where the gun is pointing using a Wiimote with its sensor bar on top of the TV through a Raspberry Pi, and feeds the positional information to an Arduino. He then takes the video signal from the console and strips out its sync pulses which also go to the Arduino. Knowing both position and timing, the Arduino can then flash a white LED stuck to the end of the light gun barrel at the exact moment that part of the CRT would have been lit up, and as far as the game is concerned it has received the input it is expecting.

A little bit kludgy, but simple enough. The technique is demonstrated to work with lightguns for any console that uses a composite video out.

That is freakin awesome. Someone give this guy a $100,000 prize...or something, because this needs to be mass produced. I'd buy one today.

Ha ha, people have been proposing that idea for years. Glad someone finally actually did it.

Nice to see a proof of concept.

I did think of the same kind of thing too (using a device that takes the video signal as input, and then look for position like Wii remote does, but my own idea was to put the "sensor bar" as eight LEDs around the picture), although I have never actually implemented it or even thought of implementation details much. It is good that someone has figured it out and has managed to implement it, because I certainly would not know how.

This is pretty cool!

This could be designed to look like a gun's silencer. Wii remote device sits in front of the barrel with the LED sitting between the barrel and Wii remote. Guy seems interested in trying to make this available to others if it could be done cheaply. Imagine if bunnyboy could manufacture this for retro gamers.
