How can i use all the patches on 2k9 for pc?

I have the game for PC, but i can't find anywhere some instructions on what do i have to do to have all the old teams and updates rosters. I download the patches. then in what specific folder do i need to put them if any?

thanks.

for the rosters, settings, sliders----you can paste them here:

C:\Documents and Settings\~user~\Application Data\2K Sports\NBA 2K9\Saves

Note: ~user~ is your profile in your operating system..this folder is normally hidden so you have to set your folders to show hidden files..

for the iff files or the patches themselves you can paste them here:

C:\Program Files\Steam\steamapps\common\nba 2k9

hope i was of any help..
