Can I choose which save file to use when starting Part 2?
No, the game automatically detects and uses one of your saves from Part 1 if available. If you want to start with a clean slate, delete the persistent file located at C:\Users\...\AppData\Roaming\RenPy\persistent.
How do I define relationships at the beginning of the game?
You can define relationships in the beginning by using the console to rewrite specific choices. For example, you can set $ mp.lilly_impregnated = True and other similar variables to customize your experience.
What happens if I haven't completed Part 1?
If you haven't completed Part 1, you can still play with a predetermined selection of choices. Your choices from the first game will be automatically detected and saved as long as you have finished it.
How can I ensure that both parts of Pandora's Box are in the same directory?
You need to have both parts of the game in the same directory.
Where is the 'PandoraBox' file located and how do I access it if missing?
Find the folder persistent under C:\Users\YourUser\AppData\Roaming\RenPy. There should be a file named PandoraBox in there. If that's not the case, you'll need to load the 1st game again and save when prompted to do so (at the end).
What tools are required to extract the compressed version of Pandora's Box 2?
