Alley-oop or slam dunk - When you are in your own zone and you see a player from your team under the net with his hand up, press B to pass to him. Then, immediately and rapidly press A (Shoot) and the player under the net will either do a alley-oop or slam dunk the ball.
Controller Stress Test - Enter the skills mode screen where "Three Point Contest" and "Practice" appear as options. Hold X + Y and press Analog-stick Up + C-stick Down. The "Controller Stress Test" option will appear.
Dribble behind back - When you have the ball on offense lightly press L then Y. Your player will dribble the ball behind his back.
Easy blocks - Switch to the player who is guarding the player who has the ball. Do not use R when guarding. Guard as close as you can. When the CPU (or player) jumps to make the shot, press L + R + A. Your player should jump forward and block the ball. This works about 70% to 80% of the time. Note: This requires correct timing.
Easy points - Do a pump fake. When the CPU player jumps, drive the ball in for a basket. You can also drive to the basket and pass it out for a well lined up 3 pointer. The CPU players should all scramble to the paint.
Extra points for created player - Start a game on the 12 minute setting. Allow the CPU to play, then at the end switch over to your created person's team. You will get all the points.
Hang on the rim - After dunking the ball, hold X to hang on the rim. Note: If you hang for too long you will get a technical foul.
Slam dunk - Select arcade mode and choose a team. When playing, get close to the basket -- not under but slightly off to the side or front. Press A + Analog-stick Up. If done correctly, you should go around any defenders and make a nice slam dunk.
Spin move - When you have the ball on offense, press L then Y. Your player will dribble the ball and do a spin move at the same time.
