lol! Ask and you shall recieve! Just so happens I wrote up a personal compat list on another site... I'll copy and paste it here for you and anyone elses reference....
I haven't seen one of these yet so figuered since I just went through setting up all these games... That I would post a compatability list. Please do note that people have different results because of their setups when attempting to use two daisychained Act Labs PC USB Guns.... Therefore do keep in mind your results could be totally different than mine.
Only games that feature multi player gun support are included in this list. My setup is a 27" VGA Vision Pro Monitor running at 800x600 with MAME32Analog+ 69.1 (Note later build). Commandline options added in each games ini. file are...
Lightgun
Switchablemice 1
Lightgun2b 1
Guns are daisychained - VGA out to gun 1, to gun 2, to monitor.
IF using Analog + MAME (Which is most likely the case if your using PC guns).... You will have to use "mouse controls" from the "tab menu" to set which mouse number is each gun, first use the regular game control mapper to set the buttons to see what mouse number is each gun. You will probably have to go back and remap these keys afterwards. In fact you may have to do so several times just for the game to recogzine the button! So if it don't shoot.. Keep remapping till it does! Also some games would have crap calibration but i knew the guns and buttons were mapped right... Simply exiting and reloading seemed to fix the prob.
Now onto the list:
Alien 3 - Good.
Area51/MaxForce - Good but had to use in game calibration repeatedly till I got a good accuracy on both guns. Off screen and secondary button reload both working!
Bang - Good
Beast busters - unplayable due to major accuracy problems
Catch 22 - Untested (2player?)
Dragon Gun - Good
Golly Ghost - Unplayable because of poor calibration.
GunBuster - Good
Gun Bullet - Untested (2player?)
Jurrassic park - Playable but accuracy off more than an inch.
Lethal Enforcers 2 - Good
Locked & Loaded - Untested (2player?)
Lucky & Wild - All ---fouled up beyond all recognition--- up! Unplayable.
Mechanized Attack - Good
One Shot one Kill - Good
Operation Bear - Untested
Operation Thunder - Good
Police Trainer - Good
Revolution X - Good. Turned off 'gun 3' from dips and set calibration for all guns by having sysmouse as the control for both guns, and set values with that (Trackball) to 00,128,255. Then switched gubns back from mouse controls, mapped buttons, escape then reload... Viola!
Sharpshooters - good
Space Gun - good. Think I had to do a similar in game calibration as with Terminator 2 and Revolution X but can't remember!
Steel Gunner 2 - Unplayable due to severe accuracy problems.
Target Hits - Untested (Dual gun game?)
Termnator 2 - Good. Set calibration for all guns by having sysmouse as the control for both guns, and set values with that (Trackball) to 00,128,255. Then switched gubns back from mouse controls, mapped buttons, escape then reload... Viola!
Tickee Tickats - Good
Underfire - Good, but reload off screen does not work (Older MAME build perhaps?)
Zero Point - Good
Zombie Raid - Playbale Sort of! Took with a lot of going back and forth with in game and gun calibrations. managed to get an accuracy within 2 inches but some shots still go wild. Works good with one gun, lightgun2b and multiplemice options off. Maybe some more tinkering will get this sorted better. Offscreen and secondary button reload working.
