Gameboy Advance CPU Pinout

[Lyndon Golding]

Hi there,

I'm new to modding and have come across an issue on my GBA board. The TP2 test point has lifted and caused the select button to become non-functional.
My aim is to fix it with a bridge wire, but instead of scraping traces I would like to find what pin exactly this trace for the select button connects to and solder there directly. Does anyone know the pin out or have a well labelled schematic?

Thank you for any help you can provide.

Lyndon

TP2 test pad goes directly to the CPU ( 3rd pin up on the left side).

Dont know if the info is still helpfull with how long ago your post was, but I havent been on this site in years and didnt see any other replys.
