What's this mod?

I've bought a gameboy advance with a malfunctioning screen on ebay with the intent to do a shell and IPS screen swap. But as I opened the console I noticed a few wires and tape that, as far as I know, aren't originally part of the gameboy advance. So this has probably already been modded before. But this is my first time opening a gameboy advance (not sp) so maybe it's actually normal?

I've searched a bit and I can't find anything on this kind of mod. Does anyone know what this is meant to do?
