PacDrive Configuration?

[Cooljax]

Hi all, I just finished wiring up a PacDrive to my control Panel. It is a old pacman Cabinet with 6 buttons one player. When I go to the LCD/LED plugin with Gameex it seems to be fine. When I load Gameex all the buttons light up when it starts. When I go threw my Mame games the lights do not change. When I load a game Player 1&2 start light up as well as player1 button1. But it does not seem to change for any other game. I am a little lost with where to go from here? I don't know if my MAME is missing something or if I have something configured wrong with the plugin? Is there a Dummy or Idiot guide for setting this up? I also had to wire this up with 12 volt. I don't know if this would cause any problems. Seems to work fine other than lighting up the buttons for Mame games or scrolling threw Gameex Mame games. Any help of advice would be most appreciated!
