Okay, first of all, this cheat edits a game file. I highly suggest that you save another copy of the file you are about to edit before going on.

Step I- go to "my computer" and look up "Constant.ini". Spell it the way you see it here or else the computer will NOT find the file.

Step II- open the file up, and scroll down to "Playerstartparkmoney", and when you find it, edit to whatever you want! WARNING: you cannot go beyond $999,999,999,999.
