Pokemon Blue Cartridge Repair

So, I have an old copy of Pokemon Blue that stopped working when I was a teenager, I’m 28 now, so it’s been quite a while, but I always keep it around just 'cuz. I opened it earlier this year to look at it, but since I have no experience in this sort of thing, it’s not like I could figure anything out. I did remove the battery when I opened it before, I still have it, tho I don’t know if it matters.

Could someone figure out what might be wrong from this? The game simply never boots or has anything other than a black bar when I try.

Since I made this account to post about this, I’m guessing that’s the reason I can’t upload pics, so…spaces.

Try cleaning the contacts with 100 proof ipa and blow out the dust it might just be that mate
