Do it yourself manually when you create a new player using cheat engine
and follow @etchedos guide
Right, I figured out the method and it's quite simple. What you do is go to create a pro and the attributes or physical tabs. Pick a stat and scan for that number with the search set to 4 byte. Once scanned, go back into the game and change the option on your tab and the stat you selected will change, input the new number and do a next scan and you should get one remaining option. Double-click that and then edit it's value, select the box so that it sticks.
Go back into the game and change the tab and then go back, your stat should be changed to whatever you inputted. Do this for all stats you want changing and then save.
I edited every stat I could in the create a virtual pro menu and my guy was a 93 overall and the height/weight I wanted (5 ft 2 and 150 pounds)
One final point, when you change an option you might lose your changes. Don't worry, if you switch tabs it'll right itself.
