I just got the game and have no idea about what has been cracked so far
but, i have found a way to edit existing players using the ingame editor
what you have to do
1. create a player
2. open the ros file in a hex editor, goto the created player, and look for bytes 226-228,(considering 1st byte to be the one that haas player id,like in cricket 2004)
3. copy them(those 3) and paste them in any existing player's 226-228
4. open ingame editor and goto "created players" you find those existing ones as well
5. edit whatever it allows you to edit
6. if you can make a better face using ingame editor do it, and you come to an END
7. but, if a player has correct default face(like aussies,english,etc.), then you better change bytes 226-228 to initial values
Another thing I've found is that byte 222 governs players height, 01 is a little fat and medium height, 10 very tall, 0f like 01 but not fat, not made any more experiments
btw, ingame editor doesn't allow you to change height,stats(and maybe some other properties as well)
