NiGHTS into Dreams

To change time, to get the Alarm Eggs out of the level, play all levels and all bosses:
When the sonic team screen appears, press the following codes quickly: A, B, Right, A, C, A, Down, A, B, Right, A (ABRACADABRA). You will hear "Aptiva!" when you have correctly applied this code. Go to the titlescreen and press this code: Up, Down, Left, Right, A + START. You will hear a sonic sound when you have done this OK. Now, go to one of Elliot's dreams and enter the third code: X, Y, Z, Y, X and press START. Play with Elliot and press PAUSE and enter the fourth code: Right, A, Left, Left, Y (RALLY) and press START. Collect 50 balls and press PAUSE. At last, there appears a menu with which you can change everything.
