Pretty much all art files. Rosters can be used if you just copy across the players.dbf and appearance.dbf files and use NBA Live 07 files for the rest of the databases.
They're called by their jersey number, because there's no speech ID included in the game for them. Unless speech ID from some older Lives works for them or there is another player with the same last name, there's nothing you can do about it.
i just remember that micheal jordan has a speech id in nba live 04 , is there's a way that i can put this speech id to higher version of nba live let's say 06,07 and 08?
