Can you tell me how I could change a player's headshape?

I don't like some of EA's headshapes on some of my players. What file(s) do I have to edit in order to change the headshape of a player? What tools do I need to have? Thanks!!!

Good question... it's too bad they didn't include that option in create a player this year... I created a monster guy (7'6" 235 lbs.) with a body like David Robinson, but he's got an equally monster head! And what's up with not including a custom "asian" face this year? They had it last year!

If you are talking about existing players, no there is no way to edit headshapes.

You can take another player's headshapes but this requires additional patching (You need to redo the face)
