I'm using the Steam version so it's possible the file is different if you got the retail version of the game.
Try without the overlay change but I suspect it's needed to enable the interface to come up where you can use it.
So far my playing around hasn't been TOO useful yet. Still playing with it to find something that "works" as expected.
Not sure how to use them after creating them. I can't select them after creating them....trying to figure that out.

The one cheat as stated already that does work well is the reveal all. Removes the FOW completely from the game which can be helpful but AFAIK will prevent you from making exploration discoveries which give a lot of benefits especially early on.

Seems to be limited to the demo, i'm actually thinking they might have added some kind of encryption to the file because they don't want players trying to avoid the 100-turn limit, heck it might even be defined in the config.ini for all we know.
i kinda got past the 100 turn limit. lol
burt you get stuck after you research all the tech that is available in the demo.
