you need to decrypt a file to have access to the main.rpy.
1- download the file in this
You must be registered to see the links
, you can choose not to pay to download it.
2- move that EXE file to the ./game/ folder (important to do this)
3- press and move the file SCRIPTS.RPA on top of that new EXE you download and moved, this will automatically extract its content to the current folder. one of the new files is named "main.rpy"
4- (optional but should be done because, after decryption of scripts.rpa is done, you don't need the file anymore, and you will free disk space by deleting it) if you want you can delete the RPA file you decrypted.
the game will now work with the new decrypted files. RPA files are just like a ZIP or RAR, except they are not compressed.
