I decided to mod one of these cheap sticks with Sanwa buttons and a Seimitsu LS-32-02. I had no problems taking it apart and prepping it for the new parts, and soldering the wires to the small contacts was not as difficult as I thought it would be.

When I move it in any direction it acts like it wants to move but won’t actually move in that direction, almost as if its stuck between opposite directions. I followed the various wiring diagrams I’ve come across on this site, but have had no luck. If anyone here can help, it would be greatly appreciated.
