The console is not to do with the game itself, but a way to change values within the game itself, for example money. as long as you know the commands.
unfortunately I don't know what the commands are, but to access the console.
first get an editor, I recommend Notpad++ it's free -
You must be registered to see the links
then look for 00console.rpy it can be found in this folder C:\[game name]\renpy\common
right-click on it and click edit with notepad++
look for "config.console = False" and change "False" to "True" no quotations
Make sure to save, before exiting Notepad++
Next run the game and use Shift+O (NOT ZERO(0)) to bring up the console.
but if you want it to be a little easier, you can try editing the saves
