I just got an authentic copy of Pokemon Blue from eBay that I’m wanting to fix. The issue is that there is a huge black square where the characters are set to appear. How can I fix this?
Also, this is the first game boy cartridge that I’m actually going to attempt fixing, so I would like some pointers too if that’s alright with you guys. Update (08/07/2022) I know that the game will definitely need a new battery, but now the game won’t get to the title menu whenever I put a cartridge in. Update (08/05/2022) @hellomacos here is my multimeter. What setting do I need to set it on?

Hi I believe this issue is caused by corrosion on the PCB or loose pins You may need to repair some traces by soldering them back with jumper wires but it will probably just need some isopropyl alcohol and cotton buds to clean it up As for loose pins you will need some fresh solder and flux for them, it’s not to hard you just need to solder them down carefully Here’s a video on fixing them up! https://m.youtube.com/watch?v=xYUW0uVBp0… Hopefully this helps If you need any help just ask Thanks:-) Edit: if you clean the spots I have high in red with isopropyl alcohol it may resolves your issue If not let me know and we can continue diognostics:-)
Look at the chip on the bottom left of your pic. Left side has corrosion on quite a few pins. Clean it off with some ipa and re solder every connection on the board.
