Hi Marc Steene! Can you share the password from the game Slender Mansion, namely the archive 'game.enc'. There are many different cool scripts, such as lightning, slender AI. I belong to those people who in 2021 are still trying to do projects at FPSC. Waiting for reply.
Wow, I can't believe FPSC is still going! Unfortunately I have no idea what the password is, it was packaged with a tool called Vishnu which I think sets the password. I do know that Vishnu extracts the raw files out to some location in your user temporary files so they should be possible to find with a bit of digging.
