So everyone, myself included, has been pissed about having the ps3 version of 2k12 being stuck at the loading screen. The solution is here. Go to GAME DATA UTILITY, (NOT SAVE DATA UTILITY (thats where all your my player, association etc saves are) , when in GAME DATA UTILITY delete the “NBA 2K12 ADDITIONAL DATA” and “NBA 2k12″ files. Then start the game and it will tell you to update the game, do so, start the game again and it will load and you can finally enjoy your NBA 2k12 on ps3 once again.
* The files you delete are nothing important, its the files that are installed to make the game start faster, no saves attached, they get reinstalled once you start the game, nothing to worry about.
