As I previously speculated here, a new roster update for NBA Jam: On Fire Edition was indeed in the works and is now available to download. To get the update, simply go to the Online Arena and the new roster will be downloaded automatically, along with all the necessary assets.
In addition to updating the rosters accurate as of the trade deadline, the second roster update also adds the following players: Kyrie Irving, Jimmer Fredette, Jeremy Lin, Derrick Williams, Tristan Thompson, Brandon Knight, Kemba Walker, MarShon Brooks, Nene, DeAndre Jordan, Darren Collison, Aaron Afflalo, Roy Hibbert and Kyle Lowry. It seems that the new players are not called by their names, suggesting that no audio updates are included, but their addition to the game certainly balances out the rosters after the first update left a couple of teams’ lineups very thin.
