Well, the default JAMMA standard is for mono (as you already know), but I believe there's been some revisions to the standard to support 2 speakers. And many JAMMA boards do in fact support this stereo output. So, if you wired in the second speaker to the correct pin on the JAMMA edge connector, then any JAMMA board that has on-board stereo through this output will work. But then any jamma board which is only mono will produce sound in only one speaker.

Then to further complicate matters some boards, like my Galaga 88 output MONO through the edge connector, but supports stereo through seperate connectors on the circuit board which I would have to wire up to a 2nd speaker...

It's all very confusing isn't it?!

the only board i have is Aero Fighters, i only use it for testing..right now im reconstruct my cab and turn it into Jamma and MVS cab, so it can play both jamma and neo geo games, and i need to put in one more speaker anyway, cause MVS used stereo..
