be able to do almost anything with this ( change postions, heal players, change age, edit attributes on all players. etc) you will need a modded xbox or action replay, this works with ps2 as well. and you dont have to start franchise over when usign this. just load up ur franchise or roster then .Zip it then load it with the editor then extract the zip the either ftp or place back on action replsy.
