Question pls answer

I have few questions...can you edit gears in game which i can use for players with NBA logo on it??? can u edit headband...4 example replace that retro multicolored with basic nba headbands but with logo on back or on another sides?? And where can I find tutorials for fsh editing or making??because I was seraching it and i Cannot find it THANKS

You can only edit the headband like you described by using the EBO editor
You have to edit every hedshape on your own then. Search the forum for more instrucitions. There´re enough tutorials for fsh just use the search function
FSH files are opened with FSHX (download at nba-live.com)
Please write exactly which files you want tot open and may I can help you
Hope I could help
