yea, you just have to add a new jersey into the teamgear.dbf file and make it cl01, cl02, cl03, or whatever is not taken. technically i guess you could have 99 jerseys for 1 team (cl01-cl99) but that wont happen. good luck Big Answer.
I wanted to say how great of a job I think kobe8rice41 on this uniform. I also want to thank nba2kstuff for providing the technology to do the player name letter color editing. ehlomint was also very helpful in that respect.
