I finished the game and realized that there is no end of game save function. After the credits roll, it showed Tidus in the Farplane, then the logo, after that, its the "The End" screen and nothing else.. I had waited over 10 minutes at the last screen too and nothing pops up. In that case, is there a New Game+ function? If I am not able to save game at the end, then there shouldn't be a New Game+ function right? If this is right, then where do I get the remaining 10 movie spheres? Some of the theme songs at the Tower of the Dead were amazing!!!

Unfortunately, the New Game + function does not exist in X. You'll have to totally replay from the beginning.
