No need for a mod or RPA extractor. You can do it with any game just by changing a config
Open the folder where your game is
Navigate to renpy/common/00console.rpy
You can open this file with any text editor, like notepad
Locate the lines that say
Code:
# If true, the console is enabled despite config.developer being False.
config.console = False
Just replace "False" with "True", save and close the file.
Then once you are in game, you can open the console using Shift + O
I use it all the time to follow some variables.
