Ocean Trader Cheats

Make an investment in the bank (10,000 $ over one month). Save the game. Quit the game.

Use a Hex Editor and open the savegame (game?.sve)
Search for 10 27 00 00 10 27 00 00
Change the numbers to 00 CA 9A 3B 00 CA 9A 3B

Start the game and reload the savegame. You now have an investment of 1,000,000,000 $ due within a month. That oughtta help out a bit.

Oh, and there's nothing that prevents you from making several investments at once, I was well satisfied with 3 billion buckaroos. By the way, choosing a financial target as single goal is folly, and will cause you to automatically win the game. Select all goals at max.
