Just an FYI... in all honesty i dont think the game will work... looks like the contact pins have some kind of liquid damage on them and normally when you see that it meas either the cart was submerged in water for a prolong period of time or the internal battery exploded and damaged everything...
Don't bid if you have that suspicion. I bought a box of old games for my NES collection and this was at the bottom. I'm sorry it offends so many of you, but as a gamer I know it's better to sell (or in this case auction it for no money) than to throw them away.
