yet another Naomi Error thread "...not enough switches"

[kingcar]

Hey Guys,

hooked up my Naomi 2 with Netbooting after a long time and it made me regret it to hook it up again. XD
My setup:
Blast City, 001 Loom
Capcom i/O ( getting 3,32V, 5.1V and 11,78V from the PSU with the setup hooked up and running. I measured this right from the Jamma edge and the 3.3v from the Capcom I/O JVS Power plug.
The PSU is the Blast Original one.


So the Error i'm getting has been only on Capcom vs.- SNK 2 so far.
"not enough switches"
This is the first time I ever see this.
All Buttons are hooked up to the Cabinets CP and the Kickharness is connected too.
So I tried another 6 Button Game CVS1 and Pro which is running but is missing:
HP, MK and HK (button 3, 5 and 6 that is)

So I checked Akatsuki Bltzkampf which has 3 Buttons 1, 2 and 3 this one is running fine.
Other Games on the other hand which have 4-6 Buttons ale also missing Button 3, 5and 6.
Other Systems (Cps2/3) that use the full Cp are running absolutly fine.
Any ideas what it could be?


edit:
On my Supergun every game loads and behaves just fine by the way. :/

I think there's a jumper on the Capcom IO you have to switch.

3. This [...] switches between 2 player and 4 player mode. If it is set to "right", the Capcom IO will act as a normal Sega IO with 2 players and 3 buttons on the JAMMA edge connectors (extra buttons must be connected via Capcom kick harness).

Try that.

Nevermind guys.

I didn't know there was a Button that determines the amount of Buttons that are hooked up on capcom I/O
Lever was set to 4 Buttons, flipped it over to 6 and now CVS2 is running fine.

What a sunday morning. XD
