From what I read in the forum, there are many users who put help in make the Game Operation G.H.O.S.T. to work correctly with the lightgun.
I love this type of games and, of all, I only had problems with 2, the Sega Let's Go Island, but with the Let's Go Island 3D already is solved.
Only the Operation G.H.O.S.T. still does not work correctly in fulscreen mode and with the crosshair aim to work correctly.
The aim is not aligned relative to the cursor, and is never correct in fullscreen mode. But using the mouse works perfectly.
In the native mode of the game everything works perfectly, but in a small window relative to the full size of my monitor (1680x1050 16:10).
I have tested the 3 loaders that are here and in none of them I was able to put the crosshair aim to work correctly in fullscreen mode.
Open this topic, so that people who own a lightgun and have the same difficulty can share information / settings to correct the problem.
Many Thanks.
