I'd bet money on them being the same (or maybe an older version of HM's ROMs if he was too lazy to keep up with the thread)
no problem with the video sync... the problem is that this board is missing video GROUND... solder a wire to the video ground pin on the JAMMA edge to any near by ground point and your Blast will no longer be angry.The priority at the moment is the video sync. My Blast City gets very angry when I connect this board.
I know you were sharing this with some of us earlier today and I didn't have time to give you my own thoughts.Add me to the Bootleg Garegga V1 club.
The game out of the box had an error, would lock up, and would be unstable.
Doing some inspection of the shit work the previous owner did, I reflowed the TXT and BASE sockets to get rid of "AUDIO ERROR" on bootup.
That stabilized the board, and now it runs in circles.
Moving on to audio... I get none.
I decided to inspect the audio amp section.
My amp is pictured below and looks pretty worse for wear.
I assume I should replace it.
I replaced all the capacitors with their values, reflowed the amp section, and still get no audio.
Connecting the PCB to my MS9 in my NAC, I have no sync.
On my supergun, and my Wai Ya Blast City, it runs fine.
Just picked up one of these. Does anyone have suggestions on where to begin diagnosing this? I’m talking with the eBay seller and he suggests just reseating the socketed ICs. I suppose I’ll give that a shot before trying to send it back and get a refund
