Enjoy this tool for what it is.It's the first and last you will see of a madden editor.Pretty much all game save modders gave up on Madden,and many other EA games,due the checksums and what not.EA,from now on,will encrypt the living crap out the Madden files,so they can't be deciphered.M14's roster file will not be swap-able,with earlier versions of the game.They don't want people playing last years model.They want you to buy their new crap.Rosters for M12 can still be updated beyond 13,but it will take a lot more work.
