Gameboy cart does not work.
I recently picked up Castlevania Adventure for the GameBoy at a local flea market. I cleaned the connectors with rubbing alcohol and tried to play it but the game did not go pass after GameBoy logo disappeared. I dismantled the cart and discovered one of the connectors has a small black dot on it. I tried to scratch it off with my finger nail without luck. It maybe a small area of rust. Is there anything I can do? A pic of the cart is attached.

If that's rust, I think you'll have to use something abrasive. I'd start with wiemen's stove top cleaner (white paste, just a dab of it with a q-tip). The stuff works wonders. It's abrasive so if you use too much and with a lot of force you can remove the gold plating down to the nickel, which you don't wanna do. If the rust is on the surface, you could try removing it with very fine sand paper. If it's all the way through the nickel you might be out of luck, unless there's some way to solder onto it and file it down or something. But yeah, I'd use wiemen's, sandpaper on the rust, then check for other spots of rust. If you have a multimeter you could check for continuity between the pins and the chip.

P.S. If you think it's still the contacts, I made a video on how to clean NES games and the cleaning methods could be applied to Game Boy carts as well.
