Question about Modding

This may be a dumb question but I am looking for how to take an Nba 2k13 roster from your xbox 360 and put it on the computer, put cyberfaces on them then load them back to your xbox 360? Is that possible and how would I do that if so?

it is not possible to do that. You can take the ratings and other information like that between 360 and PC roster files using Leftos' roster editor, but you cannot add art to the 360 version, including cyberfaces....only 2K can do that.

Rosters don't hold CFs inside them. They are completely separate files.
