Gazillionaire Deluxe Cheats (PC)

From the Passenger Menu or the Main Menu, you can press [CTRL] - P.
  This will randomly generate a new group of passengers waiting to be picked up. We
recommend using this cheat if the original number of passengers waiting to be picked up is
very low. In this case, there is a high probability that you will increase the number of
passengers for the week. However, if the number of passengers waiting to travel on your
ship is reasonable, we don't recommend using this cheat button. It just may backfire on
you.

From the Fuel Menu or from the Main Menu, you can press [CTRL] -
  F to randomly generate a new fuel price. We recommend using this cheat if the original
fuel price is high. In this case, there is a high probability that you will save some
kubars. However, if the price of fuel is already low, we don't recommend using this cheat
button. It just may backfire on you.

While inside the Marketplace Menu, you can press [CTRL] - B
  To bring up a random commodity for you to buy. Sometimes this will payoff and other
times you'll get worthless goods. But don't worry, this cheat cannot backfire on you. If
you don't like the random commodity, you don't have to buy it. It just increases the
choice of products available for you to choose from.

From the Voyager Insurance Menu or from the Main Menu, you can press [CTRL] - V.
  This will randomly generate a new insurance price. We recommend using this cheat if the
original insurance price is high. In this case, there is a high probability that you will
save some kubars. However, if the price of insurance is already low, we don't recommend
using this cheat button. It just may backfire on you.
