I recently got this gameboy advance SP that "didnt work". Someone clearly got into it before me as multiple screws were missing and 2 screw holes were drilled out. In any case it does seen to work with a new battery just not very consistently. I assume this corroded connector is the issue? What do you guys think? Any experience with cleaning these? I really hope i wont have to replace the whole connecter it seems like itll be a hassle...
