Try the cartridge on a different console, such as a friend's console, please. If it works, your console may need some maintenance. If the cartridge does not work on any other console, it may be faulty, regardless of whether it has scratches or not.
In the latter case, you will need to contact the original store where you purchased your copy of the game to ask if you could return the product, based on your proof of purchase and the store's Return Policy.
As the developer and not a distributor, we are unable to provide you with an exchange copy of the game.
