The "console" is the renpy in-game console, just to make sure.
That console is activated by the Unren according to the explanations you see in this thread.
You jump into that in-game console mode, once the game is running, by pressing SHIFT-O, then type in the cheats / stuff from the walk through you want and then leave the console with typing "exit" and return.
After that changes are immediately available in the game.
And P.S.:
Be sure to play V0.4RC4 to avoid a nasty quest bug.
