Naomi 2 game errors ?

[neros77]

Hi

I recently got into the Naomi system and what and awesome system this is.

My setup is this:

Naomi 2 motherboard with a supergun and Capcom I/O board and extra PSU on the side all connected to my Sony CRT 21 monitor that outputs high res btw.

I looked this up and googled it but couldn't find anything on this matter so I hope you guys can help me out on this.

My two games that i have right now are these:

DOA2: Millenium
Giant Gram 2

My DOA2 works perfectly.

The error is this when I put in my Giant Gram 2 game:

"I/O BD connected to Naomi BD does not fulfill the game specs."

What does that mean do you think??

Please help me out if you have any ideas what this might be thanks.

It's not a game I've played but as far as I know it's a standard joystick/3 button game so the capcom IO "should" work. I could understand that error if it used analog joysticks but I don't think that it does. Without another IO to test with you might be stuck until someone can test the game for you with a JVS IO to know it's working, and then see if they get the same error you do with a capcom IO.

Make sure your IO is set to 2p/6shot (not 4p) inside, there is a switch for it in the capcom IO. Check system assignments in the test menu to make sure the cabinet is set to 2 player... other than that, see above (sorry it's not much help).

Oh I see!!

This is what it tells me also I didn't think that was important sorry.

Name: No Brand: Naomi Converter98701:ver2.0
Players: 4
Bits: 10
Bytes: 2
Coin Chutes: 4
A/D Channel: 8

"Players: 4" Could it be I need to switch this as you say?

I fixed it!

I had to go inside the Capcom I/O and turn the switch to 2p/6shot!

So happy I learned this..Thank you very much sir.

Very good help!

No problem, glad you got it working As far as I know the only reason to have it set to 4player is for power stone 2.
