Use USB game pad on JAMMA

Looking for a solution to connect usb controllers to jamma cabs.

I have seen the USB2DB15 and I own a couple of UD-USB decoders but I need a solution for about 25 cabinets so I would prefer not to wire buttons individually.

Is there a reliable solution that doesn’t require individually wiring the buttons? Maybe one that connects directly to the PCB’s jamma edge and then to the harness like in the image below?

Also, if I did use USB2DB15 or UD-USB decoders, how would I connect them to the jamma edge? I've only been able to find examples of them used for superguns.

Something like Axunwork JAMMA Extractor could work: It gives you DB15 port to which you have to then connect USB2DB15 decoder. Probably an overkill of a product for the mentioned use. Probably you ask someone here to design/make you a simple DB15 Extractor for your use (something like this)

Found a link with more pictures if that helps.

Thanks. It looks like the two most reliable options right now are to get the USB2DB15 and then:

pair the DB15 version with something like the Axunworks jamma extractor
or
get the CS version and solder the ends of a Brook Fighting board cable to a male-female Jamma extender.

I'll try to update this thread later in case its helpful to someone else in the future.
