Street fighter 2

[BaldiGit]

Hi all,

I'm hoping you veterans of the arcade machine art can help me.  

I have been given an arcade machine for Xmas thats in bits (I know.... its a bit early. Or late maybe). I've got it back together and working but the extra buttons on the kick harness refuse to work.

My PCB is a little strange. If I google for images of street fighter PCB's, it looks identical to a Street Fighter Final Fight. But all the eprom slots are full. But when I got the game running it comes up as
a Street Fighter 2 Champion edition. It looks like a genuine JAMMA Capcom but has no kick harness header on the small top PCB like the usual street fighter 2. But there is a 9 pin header on the middle medium sized board.

Acording to the pinout for the kick harness there should be 2 grounds at one end or the other. But my board has no continuity to ground at either end...  

My fear is this is some hybrid upgrade of a Street Fighter Final Fight and the header isn't for a kick harness as final fight only had 2 buttons.

Any ideas anyone?

Not sure how to post pictures... The insert image button just adds text. If someone can tell me how, I'll post a picture.

All's well...... Sussed it out.

Used a fly lead from groung and went along the pins till one of the charicters on screen kicked.

It's not in the same order as the standard kick harness at all....??

I'd move the button connections around until it is in the right order. Should be an easy fix! Glad you figured it out.

Thanks for that. I've cut up the connector and manage to get it on in what I think is the right order. Not sure what kicks what yet...!!!
I've ordered a new connector so I can do it correctly.

Now I've noticed some of the sounds are missing.... The musics ok, but no fighting sounds accept the odd squeek from the speakers. I've checked the 5v+,5v- and the 12v and that's ok.
the volume pot seems to work smoothly. looks like a board issue.
