Hint: Switch scoring:
Press Start to pause game play when the CPU is about to dunk the ball. Move the play back in time slightly, then press Start to resume. If done correctly, the CPU player will drop the ball and not score. Gain possession, then run past half court to have the ball become stuck under your basket. The ball will turn invisible, and any points scored will be credited to your team.
