Way overdue, but I'm happy to announce that the first run of my JAMMA extension harness is ready!
  • Supergun dedicated (not only for the HAS)
  • Hard gold plated JAMMA edge contacts
  • ~60cm cables length (~68cm total length)
  • 2x16AWG for GND, 2x16AWG for +5V, 1x18AWG for -5V, 1x18AWG for +12V, 22AWG for everything else
  • DIP switch to enable/disable buttons 4, 5, 6 outputs on the JAMMA connector
  • Compatible with the HAS kick harnesses (and it doesn't require any AUX harness between the HAS and the extension harness)
  • Clean design with solid copper planes and no unnecessary vias

Price - 60 EUR


Optional items:

Shipping via Fedex International Priority (2-3 days delivery) - 14~17 EUR for one harness, 18~24 EUR for two or more (or if the order value exceeds 90 EUR).

I can start shipping them starting next week.




Apologies for photos quality, I'll snap better ones in the next few days.

Hey RGB, could you make a 150cm (5ft) version of this?

Great to see someone making a high quality JAMMA harness. I love the design!

Just to check I've understood right... I'd like to be able to use the harness with both a Minigun and a Japanese control box that uses a CHAMMA-style pinout (buttons 4, 5, and 6 on 25/c, 26/d, and 27/e). Am I right in thinking that adding the optional CPS2 connector would let me use both superguns with the same cable (by plugging in the Minigun's CPS2 kick harness as an AUX harness or leaving the connector unused for the control box)? Or does adding the connector mean it always needs an AUX harness?

Am I reading this right? This can be used with other super guns other then the HAS one? I have the Windy ATP 300 and was wondering if this is compatible with that supergun?

the atp300 already has a long harness. Were you looking to replace it or make it extra long by doubling up?

It will work, but generally it's not advised to use long wires for DC voltage, especially when you deal with a few amps at +5V. The longer the wire, the greater the resistance (=voltage drop), meaning even thicker wire might be needed here to reduce resistance. Perhaps it would be better to replace the ATP300 supergun's JAMMA harness altogether?

Thank you for your honesty RGB, I appreciate it. I do use a jamma extension on my arcade cabinet and it's one of the crummy Chinese ones. Would this be a good alternative to that one?
