Trouble with PS1 Dual Shock Hack

[SukkaFoo]

Sorry if this is the wrong forum for this.

Anyhow, I've cracked open a PS1 pad to use in an arcade stick. I've got all my wires in the right place and each button/direction is working properly. The problem comes when I plug it in to a PS2. The directional analog stick is always registering as being held in the up possition. If I reach in and push the analog stick up, then release it, it acts normally after that.

What is going on? Did I cross a wire somewhere? How can I get it to just work normally without having to press the analog stick every time?

Thanks in advance!

Sounds like your PS1 PCB is defective. It could be a flook.  Double check your wires again. Did you solder, or did you do the solderless hack? For future reference, I'm sure you did it, but always plug in your controllers and make sure they work before you hack them. That way, you know ahead of time the PCB is ok. Sometimes when you buy used PS1 dual shocks, you never know what the previous owner did to it. I have found juice stains on PCB's before. I've heard of people hacking controllers, and the PCB suddently stopped working. You may have to hack another PCB, just to make sure it's not your PS2.

One more thing, if you crossed a wire, the directional probably wouldn't work at all.

That ovbiously seems like you messed up a wire somewhere. Double check everything, including the ground and that UP wire that you are takling about and you should be OK.

Aaaaand I went back to test it today, it works just fine. Now I am scared. Do I want to finish wiring it into my new stick and run the risk of a strange malfunction durring a tournament game? This would also save me from driving all over the tri-state area looking for another fresh PS1 Dual Shock to work with.

*sigh*

I wouldn't think you'd have a problem with the analog from your wiring. I'm assuming you didn't try any hackery involving the analog sticks themselves (or soldering to L3).

How many times did you try it in the system?  If the stick was not centered when the console starts up it can screw with the calibration and do things like that. The couple times that it happened to me with a non-hacked pad I just moved the stick around and it corrected itself. Maybe this is what happened. You said you had to "reach in" and push the analog stick. Was something pushing against it inside? Could also be a defective pad.

If you're hooking it into a PC, you should be able to use Windows' control panel or a third-party utility to verify the accuracy of the inputs. You stated it wasn't working in the PS2, but where was it working properly before?
