Hex Cheat:
Open the file "User.log", or "user1.log", and go to the number 7792.
You´ll see a window in the lower left corner with several numbers (64-bit signed, 8-bit short, osv.). The number you should be interested in is 32-bit unsigned. It should be 5000 (what you start with).
Click on this line and change it to what you like, up to $999,999,999. If you put in a billion, you automatically win the game and restart with $5000.
