I think you dont know NBA 2k9 patching potential. In create team you can only create 12 teams. In create player you can only create 100 players so you cant create 16 teams... Also you cant change team names and player surnames. So your project is impossible.
We can create 10 custom teams + nba 2k, 2k china, 2k sports, vc, team jordan, and we took one like international... For now, we can't change team names.
Sorry....but there is one bad news.....we didnt succes to build 16 teams....it is only possibile to create 10....So we must delete 6 teams from patch....
This is the list of new teams...
Unicaja Barcelona CSKA Montepaschi Macabi Real Madrid PAO Partizan Olympiakos TAU
One more bad news too...Becouse i m working allone i will relesed at the end of february....If i can get some help in Potraits i will relesed earlyer..... Anyone who help he will be in credits....
