The manuals are seriously wrong with the dip switches, and if you review them carefully, you will find some sections are correct and some are incorrect. You really want to know what's what, flip a dip switch and look at that screen in setup and it will tell you how the game is interpreting it.I was also reading the manuals for both Gauntlet legends since that's what this cab originally was, and a Gauntlet dark legacy manual and checked all the led indicators codes with them. According to both of these, the LEDs are giving all normal codes EXCEPT if this sound board was changed out, then led 1 flashing indicates a power fault in the Dark Legacy manual. I don't think it is the newer board though considering it had the Rev 1 chip in it. Manuals are also both seriously wrong on all the dipswitches, at first I thought maybe this was set to standard instead of med res, found the respective switch which was u12 switch 2, and that caused this mess lol. Flipped it back and power cycled and it's back to "normal". But still I feel like one of these dips has to be incorrect or something with the jamma is off.
In any case, this is not a dip switch issue. At this point I would rule out voltages by waiting for it to screw up and checking them, and then I would suspect the video card if everything plays perfectly but the graphics are screwing up.
