Hi there,
How can I open the console to enable the cheats?
In the retails versions, you've got to enter ~ (Tilde) or @.
Afterwards you enter SISSY and are now able to enter cheats like
- alamode for the God-Mode or
- abouyandhisdog for dog bisquits.
The ~ and @ seems to have no effect in the gog version.
Thanks for help

Press ~ or @ to activate the console window
Cheat Help

Just press tab.
Or you could beat the game and get most of the cheats in the menu, wont take long, games short and easy :) (unless you crank upp the difficulty)

Thank you! I've managed to reconfigure the key "F12" to open the console via the console scheme option. Somehow, the standard key has had no effect.
;)

if someone has solved your question, please mark their post as the solution! :D
