Decompiling the game
Fortunately, this game can easily be extracted and decompiled. This makes modding much easier–if it was hard, there probably would be no modding framework.
Easy way
A tool for this has already been written for you that can do it for you automatically with little to no input. Just double click the program and it should automatically find the rpa file for the Steam installation. If you want to decompile the default Steam installation, the place it gives you by default should work fine but you can choose a different install if you want to.
Hard way
Prerequisites
You will need a working Python 2 installation. To check, open up a Powershell, command prompt, terminal, or equivalent and execute python --version.
If you get an error such as
‘python’ is not recognized as an internal or external command, operable program or batch file
then you have improperly installed Python.
If you get an output that starts with Python 3, you have installed the incorrect version of Python.
If you get an output that starts with Python 2, you have installed the correct version of Python.
Getting media and compiled source code
This assumes you know the basics of command line, such as changing directories.
- Open up a Powershell, command prompt, terminal, or equivalent
- Make a new folder anywhere and change directories to the new folder
- Copy the archive.rpa from the game directory in the installation folder into the new folder
- Download rpatool and extract the file
rpatoolinto the new folder - Run
python rpatool -x archive.rpa. It might take a while
After the command is executed, a whole plethora of files and folders are made in the new folder. For now, ignore all files with the .rpyc file extension.
Getting the source code (Only required for hard way)
Source code is the human-readable version of the game. All dialog options, games, and spoilers are in these files. However, the code is compiled into Ren’Py compiled files. They have an extension of .rpyc. To get the source code, we need to decompile the game. The source code has an extension of .rpy
- Download _unrpyc and extract the zip file into the new folder
- Run
python unrpyc.py . - Optional: Remove the .rpyc files
