I see that the GALLAG pinout includes 12v... what does 12v do for a GALLAG board? I ask because I just got a Gallag to JAMMA adapter, the JAMMA cab I am running in does not include as 12v line I don't believe and when I attempt to run the board I get the "explosion" sound at the begging looping with a bunch of crap on screen... then the "explosion" sound stops as the standard GALLAG text appears only to loop again through the garbage screen (but without the sound)...over and over.
