Try using your soundcard as an oscilloscope. It might help narrow down what's going wrong.

Do controllers work properly in both controller ports ? Many MD models develop cracked solders at the controller ports, causing all sort of headache...

Yep they work properly. I considered that as well.

Here it is with all new through hole parts. Still nothing. I'm really at a loss. I wish I could find someone electronically inclined who also owned one of these guns. You guys have been great helping based on theory and what should work in practice and I thank you for it. The only thing that is original on the pcb right now is the photo sensor but I have tried 2 others. I'm leaving this one on it for now as I do believe the sensor works based on previous testing.

I'm gonna put this aside for now I think. Not very often I call it quits on something but I really don't know what else I can do at this point.

OK so now I'm finding out that ALG used a different hit detection method than Konami did for their gun games and
hardware. Still I would think this homebrew test program should work as it's for all 3 kinds of lightguns but I'm still rolling snakeyes
with this POS I have here..lol..

I contacted the author of that program to see if he has any further information on this matter.

Related link to the test program:

Related link to info about GAMEGUN's supposed universal compatibility that is slowing showing to be false:

Youtube video of a guy using this gun with ALG games working and then he tries Lethal Enforcers 2 and it doesn't work at all.
The video isn't in english but that really doesn't matter, just what he's testing. It's near the end of the video where he tries
out lethal enforcers 2 on the Sega CD. I linked the video around the right time. Man o man this is turning out to be an expensive
debunking of internet rumor. Guess I'm taking one for the team on this one.

Odd how this is all working out.

Do try using your soundcard as an oscilloscope. It's not great - it's low bandwidth, and there's drastic filtering, but it really should show if the signal is coming through.

I'm just gonna covert this to a player 2 "pink" justifier gun I think. Clearly after all this testing and research the American Laser Games GAMEGUN is not compatible with justifier or menacer games at all. I'm happy this is now at least "out there" to discredit the rumors and false claims that it could. Also thanks to that one fella on youtube for posting the video testing all the ALG games and the Lethal Enforcers game at the same time showing first hand it will not work.

That's really weird. There's nothing obvious about the schematic that would make it obviously incompatible with both the Justifier and Menacer - there just aren't that many ways for a lightgun to work, given that the Genesis only supports "capture" on the TH pin.

I was told that the LM311 leans to it not being able to be compatible with the Justifier as it is an analog chip? As for the menacer part, at this point I'm just so worn out over this I'd rather just be happy with the information gained from this venture and turn it into something I can actually use like a P2 gun as I'll play the hell out of Leathal Enforcers long before I buy another Sega CD unit or play those couple FMV games that ALG did. :)
