Hi everyone, I have a small problem and not sure on how to go about it.

I have a Naomi motherboard with a Capcom i/o thats connected to a (Jamma to MVS) connector, which connects to my MVS cab. The picture and sound work great, and buttons A & B work fine as well. The select game button takes me to the menu system settings. But button C doesn't work at all. Now I am playing CVS1 which is a four button layout. A=Jab, B=Fierce, C=Short, D=Roundhouse. Now currently the D button is registering the short attack.

One thing I did notice was on the input test it reads shot1,2,4,5 there is no 3? So Thats why D is at position 4. Now I have no idea how to switch this. Can you remap the buttons in the settings?

Do I have to install a kick harness? And if I do where would that be connected on my MVS harness?

Also is there a free play option for the Naomi?

Here are some pics:

It's been a while since I've had a NAOMI setup, but I do think the kick harness was required. If it is, you'd have to directly connect them to the buttons for it to work. Maybe this site will have more information for you.
 
I read in another thread some time ago that you can bypass the kick harness entirely in MVS. the harness on the input board allots for all the required inputs.

you may however have to add extra wiring on the control panel side of the connector. I think I did this with regular .100 (don't quote me on this size) molex pins, I had to add an input wire to run Zombie Revenge in a Virtua Tennis cab (add the 3rd button).

however, in my journey of grounding random pins in those harnesses... I stumbled upon some 5 volt lines in there and wound up resetting the machine several times. :p

I encourage you go to a NAOMI-specific forum and ask this, cause I highly doubt the Circus Charlie/Crystal Castles bunch here are going to be able to help you.
 
I don't know about the adapter you are using, but if you were using a normal naomi IO you get up to p1/p2 sw5 via jamma connector. http://img259.imageshack.us/f/naomipinoutxj2.jpg/

Since you are using the capcom IO, its a little different as there is the 2p and 4p switch that switches between what the kick harness does.

I'm not sure why you are missing sw3 though...Link to your adapter?

A lot of people seem to think you need the capcom IO for kicks, but almost every IO variation supports extra buttons, the capcom IO is nice because of the nice built in sound amp, its the only IO board to support 4players, and it looks nice...
 
Wow,

Thanks everyone for the feedback, Thinking about just getting me a Jamma cab instead of doing the converting on my MVS cab. I really dont want to rewire things, Id rather do it on a straight jamma cab with a 6 button layout.

Ive been buying a bunch of Jamma PCB's, mostly fighters with 6 buttons so I guess I will wait.

This info will come in handy when I wire up my other cab. I will post pics of my progress :D

Thanks guys!
 
Thanks!

My kick harness came in yesterday, set it up and now it works! Set the settings on the MOBO/capcom i/o to a 2 player setup and just pluged in the wires to my buttons with the guide that came with the harness and BAM! KICKS ALL DAY! Im guessing the MVS only recognized A and B. The kick harness was connected through the capcom i/o, that thing is great!

Well it works now!

Anyone here have any info on NetDimms & Netbooting? I found this...
