Indy Heat

On the equipment select screen (before you enter your initials), press
'P' to pause the game and type "AMANDA".  The border should flash red
to let you know it worked.  Now enter your initials and select your
driver and as soon as you're done you should notice that you now have
9 coins and 9 million dollars.  You can also pause the game during
play and type the cheat, and the next time you are at the equipment
screen you will be blessed with the coins and cash.
