BlackJack!
                 Play BlackJack while listening to the ''Crystal Theme''! All you have to do is to imput in this code once you get to
                 see the The End screen after everything (note that it will not work if you try the short-cut-to-The-End method):

                 R2, L1, R2, R2, Up, X, Right, Circle, Down, Triangle, L2, R1, R2, L1, Square, Square

                 At the second press of the Square button you should hear a sound as if you're using an item. Now press Start
                 and you'll be able to play BlackJack.
