Help with bub'n bob to jamma

Does anyone have any experience with this type of pcb http://i455.photobucket.com/albums/qq276/fast_67ford/SDC10317.jpg I got this jamma adapter off ebay, but when i plug it in i dont get any sound and i can only see the start up screen for a sec when its powering off. You can see the wiring harness pinout here http://arcarc.xmission.com/PDF_Arcade_Manuals_and_Schematics/Bubble Bobble.pdf and the adapter i got here http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=230330922884 and some guy made his own here http://spaceinvaders.7.forumer.com/viewtopic.php?t=412

Looks like the one you bought is missing the sub harness on the lower layer board.

Also in case you didn't know you need -5v for the sound.
