I see that I not was the only person that thought about putting a delay to make lightguns work with LCDs. I would like to know what kind of technique uses the Amstrad's lightgun for ZX Spectrum +2+/3 (I had one as child). I had good memories of playing Operation Wolf for Spectrum using a lightgun.

My first thought upon seeing comments mention delays in LCDs was the lag compensation feature that retroarch has. (or negative input delay, whatever they call it) It works by reading your input, rewinding some number of frames, sending that input into the game, and fast-forwarding to the frame you should be on. Probably more reliable than patching individual games. I assume it should work for most NES games, if dialled in correctly. (assuming the light meter value gets handled correctly.)
