You can activate the cheat mode by holding down [Shift][5][6], then
 [Enter] or left mouse button. The cheat mode allows you to see the
 whole world, change anything in all the cities in the world and do
 all the other stuff mentioned in  the next text.

 When you're on the "choose your civ" screen, press esc and type in
 your own!

 Version 1:
 Hold down <shift> and press 123456789t.
 Older versions, ALT-R will randomize enemy leaders.

 If you look at the civs using the Shift-56 cheat and F7, civs can go
 into "Vendetta" mode and be more inclined to go to war with you,
 charge you more tribute, etc.

 You can choose your own colours for your tribes if you use debug.
 Get into the directory and type for example --debug civil0.sve.
 When you get the prompt from the debug routine, type d for display.
 The computer will then print out the first 80h bytes of the file.
 I believe it is the third byte which is the human player.  Use e
 for edit and by changing the numbers you can get any colour
 available 00=red (but then you act like the barbarians  and there
 are a couple of other twists) 01=white, 02=green, 03=blue,
 04=yellow, 05=light blue, 06=pink and 07=grey.

 Settler cheat:
 The way it works is that, when you tell a settler unit to do
 something (build a road, mines or irrigation, for example), and you
 have at least one other unit that still hasn't been moved
 (blinking), you can go back to the settler unit, click on it to
 start it blinking again (click on its icon in the box that comes up
 when you click on the unit), and then press R, M, or I to start the
 settler working again. Then you go back and click on the settler
 again and hit R, M or I while it's blinking, and you keep doing that
 until the improvement is built (you can tell it's done when, when
 you click the unit, the icon in the box no longer has a letter on
 top of it). This works best when you have the "end of turn" feature
 on, and of course you shouldn't move other units until you're done
 with the settler. If you do this right, you can get your settlers
 to build anything you want in just one turn (normaly it takes 2
 to 12 turns)!!
