Trying to resolder my stick, getting problems

Tech Talk

I received an arcade stick as a gift. A psx pcb connected (horribly) to sanwa parts. When I opened the box, almost all the soldering points came apart on the pcb and were impossible to solder back. I went out and bought a gamestop ps2 controller for 10 bucks and gutted it for the pcb.

Well, I wasn’t able to find a schematic for a gamestop pcb (which is different than other pcbs on this site) so I had to take a good guess of where to solder. I think I found the grounds (the one path that connects to all the buttons) and naturally the opposite would be the actual input.

After soldering, I tried the stick. I can only move in one direction on both axes (only right and only down). The direction is constantly scrolling on the screen. The buttons seem to work only under certain situations. In Tekken 6, trying to pick a character, the O button is constantly going on and off for example, bringing up the Go to main menu? box and canceling out of it. Pressing X would return to main menu.

I don’t have pictures yet but I can try a bit later. However does this sound like a common problem to anyone? Some rookie mistake somewhere?

The only mistake I see is that you bought a pad that isn’t mapped out. Hit up your local pawn shops and get a Sony PS1 Dual Shock pad for $5.

I fucking botched it. The soldering point for the select button seems to have been burnt off so no solder wants to stick to it.

And when I plug the stick into the USB, the stick constantly registers Up Back. None of the wires seem to connected accidentally to any other point.
