Well, after correcting my botch on the lifted d-pad connection, I think I hosed myself. I made an error soldering the resistor to the trigger points, so I attempted to desolder and remove the resistor to repair it.
Unfortunately, both points lifted off the PCB. I don't think there are any alternate points.
For the middle hole (R1 on RDC's diagrams on x-box scene forum), I see where the trace comes off of that hole. In theory, if I was skilled enough, I might be able to solder to that trace. However, I have no idea where I would solder the other side of the resistor to. It doesn't look as if there's another solder point for the bottom hole (R3 on RDC's diagrams).
Anyone know if there's any hope at this point? I kind've think I'm screwed with this PCB, but it doesn't hurt to ask.
