if it is more than a scratch, then you may need a new game.

toothpastes
It is very doubtful, if you have broken the inner piece!! , If you don't want to buy the game new again ( or get it off ebay) then just get the ROM's and a player and no more broken games!!
If you want to get a video game to work, try lightly rubbing toothpaste on it. This will fill in the scratches. From there, gently wipe the toothpaste off with a damp rag, let it sit and dry, then try it again.
