Anna Kournikovas Smash Court Tennis Cheats

See the ending sequences:
Rapidly push Up(4), Down(4), Left(4), Right(4) on controller two when the message PRESS START becomes visible in the main menu.

Getting easy aces:
If you are serving against a slow-moving computer opponent, quickly push Triangle as soon as the score is announced and hold the D-pad in the direction opposite of where you will be. For example, if you are about to serve on the right, hold down Left, and vice versa. Your player will serve the ball as soon as the screen is reset to the center of the court, and the ball will travel past the outside of the receiver, for an ace. This works about 90% of the time, with slow opponents only.

Hint: Receiving:
Position yourself before the serve towards the outside of the court, but slightly closer to the net, so you can reach and hit any ball that comes to you, no matter how fast or wide.
