Anyone got any idea on repairing broken cartridges. Pic related.

Got it for a quid since it wasn't working, figured it probably needed cleaning or something but after going at it with some alcohol and a cotton bud I had no luck, opened it up, pins are a bit worn but nothing I'd expect to stop it working, gave them a go over with some rubber and then another go with alcohol, still no luck. The board itself seems fine, no obvious broken connections or dry joints, capacitor doesn't seem to be leaking.

Any ideas or just give up on it? it's not an expensive or even particularly great game, but it would be nice to get it working.
