I bought this used GBA SP Mobo from FB marketplace for £10 it won't turn on at all I've put a battery in it I also noticed a few issues mainly the charge port is fucked up and has ripped pads there's also messy flux and solder and the game cartridge appears to be melted

It's almost certainly fixable, but it's gonna take quite a bit of work, just from a quick glance. Good starting point would be to clean off the burnt flux, remove the obvious solder bridges(like what I highlighted), then grab the schematic and start checking things out.

Can you link a schematic?

It's on the GBA SP page in the #998610706133954830 channel, for future reference: https://github.com/Gekkio/gb-schematics/blob/main/AGS-CPU-11/schematic/AGS-CPU-11.pdf
Schematic is for a specific revision, but most things should line up okay

Wait how do I fix the ripped pads for the chargers

Depends on what the real state is. You'll need to remove the charge port to properly assess the damage. Bodge wires might be necessary

Thank you

I think I found why it won't turn on the switch looks fucked
hushed glen
looks like someone melted it

It would explain the cartridge slot
Is there a way to attempt to turn it on With out the switch

I've soldered a jumper wire between I think C2 and 2 for testing. That way it boots as soon as you connect it to a battery. Not sure how safe or advisable that is. Just something I've done in the past

Where is 2 located?

Ok I did that yesterday day but it didn't work but I think I know why now
The CPU pins are bridged
I don't have a solder wick rn
I don't even know if solder wick would even work
zenith iris
Yeah that’ll do it. Use plenty of flux!
narrow wedge
Yeah that’ll do it. Use plenty of flux!
I did that's why it looks a bit wet but I ordered a wick just to get off what's left
narrow wedge
Ik it looks disgusting r. But I think I lifted the pad for C1 I was wondering if there another pad I could use
narrow wedge
Ignore the charge port but anyways I tried removing all the solder but it still doesn't work
