ok thanks. I download Unren and put it in the directory. I type the commands in console but I dont see any changes to the items like money and favors. How do I get these additions to appear in the game?
You need to run it aswell, when it asks you what it's supposed to do press 3 to enable the console. After that you can go ingame and open the commands window with Shift + OThe "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.
