So it seems like it wouldn't be totally impossible to recreate some of the led boards diy, the issue seems to be the expensive driver board and gun 'camera'.

I wonder if any companies bootlegged stuff like this? I mean we've seen off-brand namco guns in the 'named' variety that seem to be fairly spot on copies. I just wonder if anyone tried to duplicate the driver board too, short of gutting a cab.

Following this thread for a full read through later :-)

I have Lethal Enforcers 3 with mirrored CRTs and this gun technology, but was missing the optics board for P2 and found all replacement parts to be ridiculously expensive.  Had planned to pull P1 and put into a smaller cabinet, but will need some of this information for the conversion.

I have the OMZ-2D LED from the previous post in mine.

Thank for confirming, I had heard that LE3 used this tech but couldn't find any concrete info.

From the pics I've seen of LE3 it looks as though there is a separate monitor for each player. is this the case or is it split screen on a  wide-screen monitor? I was curious of how the sensors may have been arranged with two separate monitors.

Happ wants $500 for the OMZ version of the sensor module, which makes the $200 Sega version look cheap. I'd just keep an eye out on eBay, you never know a reasonably priced one might pop up.... or you could figure out how to hook up the sega one in the LE3 guns, the used ones on eBay are going as low as $75

Yes, separate monitor for each player.  It's a double wide and the sensors (transmitters?) are maybe every 12 inches across the full width of the unit.  I think I have a couple of weak transmitters, so I was going to pool my good ones and make a solid 1 player game.  I didn't take into consideration the reflection from the mirror and possible inversion if I were to use a standard monitor config, but that would make sense I'll have to adjust for it.

Actually, you can see the 10 transmitters glowing in the video:

I think I mentioned it earlier but there's a dip switch on the Gun I/O board to turn on and off X-Axis inversion for use in mirror cabs or direct view cabs. Alternatively you can just run them in the opposite direction around the screen  ;D

I found that the inversion makes no difference as the game tends to sort it self out in calibration regardless (at least on NAOMI).

This might be of interest to some people:

http://forums.arcade-museum.com/showthread.php?t=351380

this guy adapted the Gun board for Model 2 games to work on Model 3... the important thing to note here is that Model 2 games use the standard "Happ" style Light Gun. Also, it communicates with the game board Via an RS-422 serial port.

I'm thinking if someone wanted legit Happ Light guns on a PC you could use this board and decode the RS-422 info to get the gun position.

the "Mega JAMMA" board used by Police Trainer 2, Star Trek Voyager, and Crossfire Maximum Paintball works similarly, it provides a JAMMA edge connector, works with Happ guns and outputs gun position (and other inputs) to a Parallel Port connector.

I'm not too interested in persuing this myself but for anyone looking for an arcade perfect CRT gun solution... these are two solid and reasonably priced options.

Any chance there is some type of identifier or part number on those IR sensors at the tip?

Also, has anyone taken apart the Time Crisis 4 gun for PS3 that uses the IR LEDs attached to the TV?  Any similarities?

I looked when I had it apart, there are none visible. The only place where one would fit would be the back side but you'd have to de-solder it from the PCB to check and I'm not willing to disassemble a working sensor that far.

Hello, sorry this is an old thread but it's the only place on the internet where i can find something related to my problem.

I have a Sega Golden Gun and the light sensor broke in half, i've attached a picture of it.
The code is GZH200HF, i was wondering if GZH200D is compatible with my game. Would appreciate some feedback.

It looks like the part might still be good.   

 If you detach the small board, lay the board flat,  place the detached optical section back in place, and heat in a toaster oven.. you could get the soldier to re-flow,  and probably get the part to attach just fine.

 Do some research into reflow, and temperature and duration...  as too little = no reflow... and too much.. can melt plastics and or kill components.

 I do not think the optical sensor that fell off is broke in half.  I believe its actually two individual sensor chips,  based on the 4 solder ball points
on each chip.

 New non-lead based solder has a lot of problems with good smooth flow... and as such,  there is probably a 50% failure rate on all modern electronic circuit boards,  as a result.   These failures can happen immediately,  a few months,  or even years down the road.  Temperature changes,  vibrations,  can cause the already weak connections to break free.  Also, there tends to be small micro-spikes in the process... and these spikes can break off, and cause electronic shorts.

 Also, you may first want to clean the parts with rubbing alcohol, then apply some decent quality flux.  The flux greatly aids in flow and bonding.

Thanks for the info, will try reflowing, there are some computer services around and will ask around for a profesional opinion.
Meanwhile i ordered a new part from sega.
