Let's see some pictures of the fix after you test it.
Your wish is my command
Here is a photo of what the board looked like when I got it - you can see the pad is very well removed from the board as well as broken off from the trace itself. I ended up cutting it out so I could run a completely new wire to replace it.
For those of you doing this mod - these wires are cut far too long. You probably need about half this to attach to the pads, having them longer increases the risk of shorts with other components.
I tried connecting the wire directly to the proper pin on the ARM initially, but I found it didn't stay well attached. So instead I cut the original trace as short as possible to the ARM and connected it from there. I left a bit of length in the wire in case I had to route it around components, but it ended up being a bit long. Realistically I could cut it shorter and reconnect it, but at the same time I'd rather leave it as it is since it's not shorting anything and it isn't hugely noticeable.
I then routed the wire that would normally be connected to the missing pad to the through hole that is now connected, I wrapped the new wire jumper around the outside of the through hole and then put the board wire through the hole before soldering it on the bottom side.
I then used some isopropyl alcohol to clean things up as there was a bit of burnt flux residue around and I wanted to clean it up a bit. The other 3 wires are also connected. I realised after I started it up the first time and it didn't start (gave me a quick black screen then turned off but LCD/multi were still running normally) - I accidentally switched around 2 of the wires (yellow and orange in the photo) so I removed them and resoldered them down. Always double check your wires are connected to the correct pads!
Then I powered it up and got this screen......
Then
Success!
Other than the little bit of extra wire I think it's turned out very well. Happy to say it's back to working perfectly. I changed games a couple of times to confirm it's all working properly as well.
