Knowing nothing about the Xbox
Hi xobx,
There are a lot of general soldering technique, demos on the web.
klee27x shows a bit of detail for the connections.
Knowing nothing about the Xbox, I would guess the PIC I/Os go across each push button switch connection.
Then the PIC can “push the button” for you.
Problem is the PIC I/Os have to be “high impendence” when not low, so the normal push buttons can pull the circuit low.
klee27x has done this by turning the I/Os into inputs.

One glaring omission from the tutorial, No “By-Pass” capacitor(s).
Right AT the power supply pins of the PIC (Vdd to Vss).
This fact should jump out at us because the long “wire-wrap” wire should LOOK like an inductance to us. PCB or PWB also have inductance but no so much “in your face”, obvious.
