I'm starting to think the gun itself is not working. Are you familiar with the ALG gamegun at all? I've opened it up
and I see a good amount of flux crust and possibly corrosion from the large resistor (or is this a color coded capasisitor?).
LE 1 and 2 only register the trigger in menu, neither game sees the sensor on screen or the start button. Menacer 6 in 1 doesn't register
the trigger or the start button and unless it moves the cursor on its own per chance, the photo diode isn't registering the aim on the screen
either. I'm using a CRT that I use for all my gun games and even cranked the brightness just to make sure it wasn't that and it
wasn't. I've checked the start button, trigger switch and the DB9 cord for continuity and they are each good. If I've attached pics of the PCB.
