NBA Showtime: NBA on NBC is a 2D adaptation of the 3D console game. Like the original, it is a two-on-two arcade basketball game following the lineage of the NBA Jam series.

It includes all 29 teams of the 1999-2000 NBA season, with over 100 featured players. Modes include exhibition games, a full season, playoffs and a practice mode. Options have been reduced compared to NBA Jam 99: length of quarters and overtime as well as AI difficulty can be set, and music and sound effects be turned on or off.

Gameplay is seen from the side and follows the NBA Jam gameplay of old, with two buttons for passing and shooting (on defense, stealing and blocking) and a turbo button for faster running and enhanced actions, including spectacular over-the-top dunks. Season progress is saved via passwords, and the game includes several unlockable bonuses, including additional courts with a street or a jungle theme.
