MAMEWorld Forums - Ultimarc - Dual lightguns, need assistance. Reward added, anyone?

Hi Guys,

I just purchased 2 Aimtrak lightguns and am having trouble getting both to work simultaneously in MAME. When I try configure the second gun in MAME, it configures as Gun 1 x-axis, y-axis, buttons no matter what I try. Both gun 1 and 2 will always set to gun 1 in any game and both fight over control of player 1. I have followed the instructions and tried the many different suggestions on the arcadecontrols forum and on youtube with no success.

Notes:
Guns are set to be separate ID's in the aimtrak utility, I have tried lots of different ID combinations.
I verified with the controllerremap utility that they are separate ID's and devices Both guns calibrate perfectly in windows and both control the mouse.

The problem is that within MAME (I am using 0.149 and gameex front end) they are both seen as GUN 1 when calibrating the X and Y axis for player 1 lightgun and player 2 lightgun. I have tried every possible core input option in mame.ini like multiple mouse = 1 or 0, dual-lightgun 0 or 1, etc and all the other settings on the youtube videos and forum entries. No matter what I do both guns appear to be the same gun "1" to Mame.

I have also tried different USB hubs, unplugging my USB keyboard, rebooting a million times, different games.
Also tried deleting mame.ini and rebuilding it from scratch.

I was thinking there is a way to see what mame ID's are being used and possibly force my 2 guns to use different ID's?

*Reward - I will paypal for resolution, PM me for amount.
