Sanwa Joystick Problem

I have a pretty weird problem with my sanwa joystick…
When I jump left from the 1p side, the character will occasionally jump right even though I’m still holding jump-right motion. Did anyone ever have a similar problem? Anyone have any idea where the fault could be?

Anybody? :frowning:

We need alot more details that this.

What game your playing and on what system?
Retail or Custom Arcade Stick?
If it is a Custom, what PCB you have for your arcade stick?
