I have uploaded a Max Drive save containing updated rosters for the Playstation 2 version of NBA Live 09, which you can download here
. Please note that the save does not add any created players, it simply offers the most up to date rosters using the players available in the default rosters. It also includes a listing of jersey number and position corrections as well as suggested ratings edits.
The file also includes a guide to manually updating the rosters if you cannot get the Max Drive save to work. If you don't have the Action Replay Max Drive hardware, you will need to refer to the guide and make the updates yourself.
