Hints and Tips for Command & Conquer: Generals Zero Hour
(Mac)

(First of all for this cheat to work you will have to do at least 2 skirmish battles and save, 1 lose and 1 win)

Now if you have done that do the following:
go to the zero hour folder then user data.
Once in there control click on SkirmishStats.ini and open with text edit.
Then change your stats to how you waant them to be. You could change it so you have won 1 million battles if you wanted.
