note:create a backup copy of the "skirmish.ini" file before proceeding.
heres the trick:go to "C:\Documents and Settings\User\Application Data\Command & Conquer 3 Tiberium Wars\Profiles\ProfileName" directory.use a text editor [for example notepad] to change the amount of beginnig credits [default amount is 10000] with any desired number.play a skirmish and you will see that the beginnig amount is the number you entered.

As a C&C3 Smart man. I stongly suggest doing this at your own risk, entering the wrong code in the wrong space can cause any where from minor or major dmg to the game files or computer.

instead you can just raise the ammount you start off with or just simply use one of Caliber's awsome trainers

well,if you do the right thing you dont need any trainers,and you can have as much money as you want,no more,no less.
and as I said MAKE A BACKUP COPY OF THE SKIRMISH.INI file before proceeding.So if you accidently entered the wrong code,just replace it with the original file.
