I'm new to the site and need to know what is a patch?

I can see its something you request.......but how do you d/l or what?

go to the announcements section and go to the thread that has the patch you want to download in it and find the download link

Patches are modifications for the game; new graphics, player faces, updated rosters, etc. The method of installation varies depending on the patch but generally graphics files are placed in a folder (sgsm) which the game checks before loading the default game files. Rosters are saved files which are placed in the My Documents\NBA Live 07\saves folder and can be loaded from the Load/Save menu.

Most updates are for the PC version only. When it comes to the console versions usually the only patches are roster updates, which are generally distributed by devices such as the Gameshark and Action Replay. Updates for the PC version are distributed in .zip (Winzip) or .rar (WinRAR) format to reduce the download size and save the user from having to download all the necessary files one by one. Some patches are distributed as self-extracting .exe files and have their own installation programs.

props on the info

so if ea makes the patch for live 07 will it be available for the ps2?

They'll be releasing official roster updates for the console versions which you can download if you have a PS2 network adapter, however the bug fix patch they're releasing for the PC version won't be available for the consoles.
