4th button on Sigma Raijin
« on: May 29, 2009, 02:42:14 PM »
I just purchased DDP DF 1.5, my second PCB after Futari BL  =D

I quickly realized that the fourth button doesn't respond at all (while playing and confirmed in Test mode). It took me a few minutes to figure out that my Jamma harness is just wired for 3 buttons, I never paid attention to that before since Futari uses 3 buttons only...   :-X

The other buttons are linked to a small rectangular plastic connector. The problem I have is that this thing doesn't fit anywhere on the PCB.

Can you guys help on that?

It sounds like your sigma harness has a kick harness wired - hence the small plastic connector.  If you can solder, it would be easy to just run a wire from the 22 pin sigma wafer board 4th button pin to the correspond jamma 4th button pin on your jamma edge connector that connects to your pcb's.

I just bought DFK too, and was wondering whether this would be a problem for me too... I have a capcom impress, and I've never used it for any game with more than 3 buttons that didn't use the cps2 kick harness... Is there any chance my JAMMA harness will have the fourth button wired already? (I thought JAMMA only officially had 3 buttons)
