Problem configure second ultimarc gun for second player in mame 0.159 win 8.1

[Braveheart]

Hi,
 
 I passed a lot of times to try to make my second gun work as the second player in Mame  and I can’t find a way to make it work. I would like to know if you have any suggestion to help me to make it work. It’s really bad that I can’t play with my second gun as a second player with it and I really wish to be able to make this work because it make my second gun useless.
 
I am on Windows 8.1 with mame .159. I have the same Mame config from the .153 tutorial of this thread  (I tried also a lot of differents one for testing with no result) :

Here is my actual Mame configuration, I did also some modification  as suggested from this thread that not worked, like enabling mouse and lightgun to 1
mouse 1
joystick 1
lightgun 1
multikeyboard 0
multimouse 1
steadykey 0
ui_active 0
offscreen_reload 1
paddle_device mouse
adstick_device keyboard
pedal_device keyboard
dial_device mouse
trackball_device keyboard
lightgun_device lightgun
positional_device keyboard
mouse_device mouse
I have the aimtrak utility and my first gun have ID 4 and my second gun have ID 5 and both trigger working in Windows and they are both well calibrate as explained in the instruction manuel from your website.
When I go in mame and I try for exemple Area-51 Maximum force or Operation Wolf 3, my two gun are seen as 2 blue target that I can move separatly with each gun. If I hit TAB and go in player one and player 2 config for Button 1 and I hit trigger button of my guns, each gun are seen as GUN 1, it think that my two gun are the same gun.Both guns have the same reading GUN 1 BO, but my second gun should have a different ID. If I hit F2, I can do the test for both gun, and I can start game for both player, each player is able to move the target, but if a player hit the trigger, it fire for both player at the same time as both gun trigger have the same GUN ID..
Is I am doing something wrong, or I need a different config for mame .159 or it's a problem with the aimtrak gun and Windows 8.1?
 
Sorry for my english, I am a french speaker.
Thanks you in advance!

We should have a section for Aimtrak.

And I say that as an Aimtrak owner.  Luckily I haven't had to post much on it (if at all) because others do it for me. 

Of course, that might slow down the activity on the main forum.  Nevermind, carry on
