Have a look at this board:
And be honest with me... Is this thing done?
All I get is a black screen, I've cleaned these contacts as much as I can to where no more residue is coming off. I know it sort of looks like rust on these pins, but it's actually where some of the nickel plating has come off. And whatever that is on the far left pin is under the green it seems: I'm not an electronics genius, so I don't know much about circuit boards.
Plenty of other games work on my SNES, so this cart is definitely the problem.
Should I chuck this one out with the garbage? Any ideas on potentially salvaging it?
