I would like to know this as well. The trainer says add money but it replaces money to $10million instead of adding $10million. I actually lost more money than I gained...
No it doesn't it just says money, and if you read the instructions it says this..
"Numpad 3: Money - make sure you are at the main menu and then
press this key. You will have 10,000,000 dollars."
Seems pretty clear to me. (I know you posted a few weeks ago but still worth pointing out and to tell people read things first before assuming )
