[Solved] Defective button PCB?

Hi. Just getting started on my 3rd mintypi build but I cannot get the A button to register at all. I’ve already tried resoldering multiple times to no avail and even soldering a wire from the gpio pin to the test pad and nothing seems to work :( . Any help would be greatly appreciated.
Edit: the LED pin is having the same issue too.
update: I think that gpio pin is dead because I checked continuity with the button pads on the front of the board and everything seemed O.K. Does anyone know if I could change the gpio pin the pi checks for the A button to some other unused gpio pin and if so how?

You can change the gpio. You'll just have to edit a few files. Should be a retrogame file in the /boot directory. You'll also need to edit the /home/pi/MintyComboScript/MintyCombo.py file.

The A button controls the battery monitor. So you'll have to change the mintycombo.py to whatever gpio you choose for a in the retrogame file. (Use the bcm/gpio number, not the physical pin number)

Can someone elaborate on how to change the pin and what to change it too?
