For the longest time, lightgun enthusiasts were basically forced to play with real hardware and CRT monitors if they wanted to enjoy these great games
In the last half decade or so there’s been a huge resurgence in homebrew Lightgun solutions for PC, from the premade but costly ($400+) Sinden lightguns to the crafty DiY projects like Gun4IR, which has users retrofitting oldschool Guncon controllers with the same IR cameras present in Wiimotes, and running custom software on the PC in conjunction with 4 IR sensors arranged at the corners of the screen.
If all of that sounds a bit much to just to enjoy these classics, there’s another solution which works surprisingly well: Connecting a Wiimote to your windows PC via bluetooth, using a real Wii sensor bar or one of the $10 USB versions available online, and some software for handling obscure devices like wiimotes, kinects, and PSMove controllers known as “GlovePIE” running a very simple script you can find below, to translate movements and button presses with the Wiimote to your computer:

Once you get it all setup, you should be able to smoothly use your Wiimote as a mouse, at this point you just need to run whatever emulator you want with whatever Lightgun games you want to play (Time Crisis, Virtua Cop, House of the Dead, even stuff like RE Survivor and Dino Stalker, etc etc). Each emulator will have a different setup process, but any good emulator for a system which had a Lightgun will have a means of simulating that Lightgun with a mouse, PCSX2 and Duckstation(PS1) as examples where it’s only a couple clicks to set up “mouse as lightgun” functionality. Then from there you’ve opened up access to hundreds of classic games, capable of running on crisp, modern hardware and getting an experience which is astoundingly good facsimile.
TLDR:
What you need: Wiimote, sensor bar, GlovePIE, emulator, roms
What you get: Hundreds of Lightgun games capable of running on modern hardware without a massive cost or effort outlay.
Here’s an example of someone with a similar setup playing House of the Dead 3 on Dolphin:
