Start up the game (it doesn't matter what nationality and difficulty level you pick) and sail along until you find land. Send out your men and build a colony (it doesn't matter where). When it asks you to name the colony call it CHARLOTTE (in block capitals) and press return. A message should appear confirming that the cheat has worked. If so, not only will you have a vast amount of dosh and be able to see the whole map, but you can also enter the enemy colonys and reports and muck around with them.
