Extra money:

Note: This procedure involves editing a game file;
create a backup copy of the file before proceeding.
Use a text editor to edit the "menu.ini" file in 
the game directory. Edit the amount of money in a
current saved game. Start the game, load the 
edited save game, then save it in the same slow 
with a different name. Restart and load the saved
game one final time to collect the extra money
