Star Control 2

In some versions, there is a bug which you can
use to your advantage : The game doesn't check
the amount of landing pods you have when you sell
them. This means that you can keep on selling
them, even if you have none of them....

Try it out, you'll get all the money you want!

--- Or:
You can get the coolest ship in the game (the
Chmmr) by messing around with the files in your
STARCON2 directory.

Type this at the Dos prompt:
REN HUMAN.SHP *.BAK [Enter]
COPY CHMMR.SHP HUMAN.SHP [Enter] (Information from Cheat Machine)
