Connecting a NAOMI board into a NeoGeo 1-slot Cab

[Arcade-Projects]

Hello All,

First I am relatively new to this so please excuse if my question is dumb and if covered someone else a link would be greatly appreciated.

I have a NeoGeo 1-slot cabinet (it looks like it was possibly a conversion cabinet or maybe just some sort of generic cabinet) that I want to put a NAOMI 2 system in.
My question is regarding the CP: Is there something I can do with the 4th button so I can get it to work on both systems when I move the JAMMA harness?

My plan is to install 4 more buttons and wire them as well as both "button 4's" into a kick harness but I also want the cab to work when I want to use the NeoGeo.

Thanks!
