Start a new career eg. (John Smith) and exit TW 2004.

Go to My DocumentsTiger Woods PGA TOUR 2004CareerPlayers and open the players name you created (John Smith.plr) with a hex editor (I use Hex Workshop) download from http://www.bpsoft.com

At offset 00021616 change the values to FF FF FF.
This should give you about $1.5 Billion.

This should be more than enough to complete career level by increasing your Attributes. This also should not affect your winnings. i.e. your winnings still show the correct ammount you have won, but you will have $1.5 Billion in the bank.
