Street Fighter 2: CE - Has this ever happened to anyone?

I got a SF2CE board in the mail today. I have a z-back I wanted to put it in so I took out the cps2 game and cps2 harness and plugged in the CE board and kick harness. I flipped on the power and the game booted up normal, albeit upside-down. I kept the control panel open to test the buttons, and after a few seconds of being on, smokes starts coming out of the pcb and I smell it burning. I flip it off and unplug everything.

I inspect all three boards and for some reason I can't find where the burn happened, but testing the board in a different cab, it no longer works.

Does anyone know what could have caused the board to do this? Or which part would blow like this? Never had a jamma board do this before
 
Hard to say... if something smoked then there will be some damage. Inspect carefully. Look for cracks on the tops of chips and look at all of the tantalum capacitors as those are two common sources of smoke.

Measure from +5, +12, and -5 on the JAMMA edge connector of the board to ground with your ohmmeter to see if there's a short on one of the lines.
 
Was the baord dusty or dirty?

Check around the sound section, on the bottom board.

Also, try the top board with a different, working bottom board--see if there is still life in the top board.

Most likely is you either plugged it in the wrong way up on the harness, or there is a lot of sideways slack on the JAMMA connector and you had the pins out of phase, possibly with pins in the harness bridging pins on the JAMMA edge connector.

You may have fried tracks near the edge connector. When faced with smoke it is always worth postponing panic and noting where the smoke is coming from. Once its is gone it is often hard to see where the damage is, its often under chips so completely hidden.

it was definitely plugged in the right way...

the board was pretty dusty/dirty but not criminal or anything

didn't see any blown caps
 
is your DD cab missing the key in the JAMMA edge connector?
if one is missing and a key won't fit in there I just shove part of a wide zip tie in there and trim it right off Flush.
