There are some newer version light guns which use an infrared receiver similar kinda like a wiimote or kinect so that they will work on newer televisions- but it is highly doubtful emulators will be programmed to support those drivers out of the box. I’ve yet to hear of anyone getting a light gun to work with the raspberry pi- not to say it isn’t possible but I just haven’t seen anyone solve it yet.

There are light guns such as this which are far too expensive in my opinion- not to mention they only work on windows


What would be brilliant is if someone was able to hack together an infrared receiver that would allow any remote to be used as an effectual light gun.
