Act-Labs Light Gun is here- Mame Problems

(1/2) > >>

Okay, my long wait it over and my Act-Labs gun has arrived. PC games work great. But.... in MAME I can't get any game calibrated!  It fires way off screen. I have downloaded in updated to MAME .61 ( but no luck. Do I need to do anything special to get it calibrated in MAME?

I have read a few posts on "enabling light gun support in mame."  How do you physically do this?

I think you need the windows version of it.... Mame32.. not Mame... cos I think I read their web site... it uses DirectX... so... dos version of Mame will not work with the gun...

You don't need MAME32 (although it will work), but you do at least need the Windows command line version of MAME, from

I use that version.  In order to enable Lightgun support, I had to use a command line parameter to create a mame.ini file, then edit that file.  There's a parameter in that file that you must set = 1 to enable the lightgun.

What you have to do to use the lightgun with the command line version of mame is use the  "-lightgun" option for example to start police trainer you would type

mame policetr -lightgun

I mainly use mame32 because I find it easier to make changes to specific games this way but for some games that I need a little speed boost I will run the cl version
it seems to run just a tick faster.

Oh and if your wanting to play Zero Point don't bother
the aim is off about 2" to the left and a little high! I hope sombody finds a way to fix this. That game was the main reason I purchased the gun! I have since found police trainer and now the whole familys hooked.
                                Good Luck and
                                   Game On!
