It might be just a dirty connector.
Take the cartrdge apart (1 screw on the bottom) and take the circuit board out.
Then, using a pencil eraser, clean the edge connector. Use a plain
pencil eraser (not the kind for ink, as it has ground glass in it). When
the pads look nice and shiny, take a piece of paper towel soaked with
94% (or higher) alcohol (Isopropyl is fine), and wipe any residue off the
pads.
Now, the connector should be clean-as-new. If the game still doesn't
work then the PROM inside the cartridge is most likely bad.
