NBA Jam Cheat Codes for Arcade

Mini Tank Game
Regardless of the number of players, four people are needed to unlock the mini tank game. At the match-up screen hold the buttons for all of the players ?- even blank ones ?- while pushing all four control sticks down. Wait a few seconds and the mini game will begin.
Note: A positive kill ratio, where you destroy more tanks than you lose, activates a ton of cheats!
