Been working on a "Arch Rivals" game and after I replace the rubber centering part on the joystick everything worked great for about a week, then the new rubber part broke. I just replaced it with a new one but now the stick will only register Left, Right, Down and Down??? For some reason when you move UP it registers down, not up. Any suggestions? Do these go bad? Adjustments? Thanks.

Make sure you have it plugged in correctly. IIRC, you can plug them in upside down (don't ask how I know). Also check to make sure you didn't mess up any of the vanes that slide between the opto "horns".

Lastly, they can go bad, but they are pretty easy to fix. Look at the schematics (they are in the Sinistar drawing set if they are not in the Arch Rivals set).

I made sure it's plugged in correctly and like I said, it works fine except up is down, down is down as well but left and right register correctly. I didn't remove the stick to replace the part, I was able to do it with it mounted on the CP. I guess what I should do is swap them and see if the problem follows the stick or the wiring.???
