Do you even know what Jamma is? It's basically an interface standard for connecting arcade boards to, so that you can guarantee a particular arcade board will work in any JAMMA arcade cabinet.
It's not a machine, it's a standardised connector for carrying audio, video and controller I/O from the cabinet to the board. As far as I know it's an entirely analogue connection.
All the processing is done on the arcade board itself. That way you can have JAMMA games based off Z80, 6502, 68K or whatever. The JAMMA cabinet does have any processing capabilities.
So no, you can't have a JAMMA emulator for the Falcon, or any other machine for that matter. It's impossible.
