Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Enter the "\sh3\data\cfg\careers\" folder. Select the name of the folder that is the same as the career that you are using. Use a text editor to edit the Microsoft Office Outlook config file in that folder. Scroll down to your last mission details and change the amount of reowns that you got paid. Save the file and start the game. You can now buy the biggest and hardest subs in the game.
