Released in November 1996. Maximum Hangtime was a chipset upgrade for "NBA Hangtime" that Midway sent out as a combination bug fix/game enhancement. "NBA Hangtime" came out in the spring of 1996, so by that fall, the new NBA season was starting up but the game was a bit old.

Differences between 'Hangtime' and 'Maximum Hangtime' :

* New rosters for 1997 season including player trades and college rookies.

* Hot spots : Each player has a hidden spot on the court where they are more accurate. You'll know you're on it when a pulsing circle appears at your feet and you hear a sound effect from one of Turmell's favorite games, "Robotron - 2084". The announcer usually mentions the hot spot as well.

* No trivia contest. :(

* There's no code for the outdoor court - Simply press Left or Right on the joystick during 'Tonights Matchup' to choose Stadium or Outdoor.
