Quote:4) Clean the cartridge connector. I really doubt this is the problem, because it's so new, but who knows. To clean it, I would remove the cartridge PCB from it's case. You can use a pencil eraser to clean the contacts. If you see something obviously stuck on there, you could also use some isopropyl alcohol to clean it off.
It works again after swiping the connectors with an eraser. There was quite a bit of black oxide/whatever, so I guess something was put on it during the manufactoring process (fluss? some kinda coating?), that caused bad connections after a while and had to be taken off.
Come to think about it, I had the exact same problem with a supposedly brand new Gameboy flash cart a couple of years ago, and the solution ended up being the same.
