Solo Developer Creates a Fan-Made P.T. Port Using the Fox Engine

Xavier, a solo developer working on a port of P.T., says he used AI tools during development—but not simply to generate the project. The tools were used to “debug, troubleshoot, and investigate issues” while he worked on the port using the Fox Engine.

Recent retro gaming trends have included asking coding agents to decompile games, a topic that has also drawn discussion on social media. Xavier says his work on P.T. is based on years of research.

“I’m a solo developer and I’m free. I ported it because I love the game,” Xavier said. “No one hired me or asked me to spend countless hours on this. I’m sharing something I’ve worked incredibly hard on simply because I want other people to enjoy it too.”

Why the P.T. Port Matters for Game Preservation

Beyond giving curious gamers who never had access to the highly limited PS4 version a way to experience the game, the port could also interest digital preservationists. Maintaining public access to historically significant games such as P.T. is an important challenge for future generations.

Henry Lowood, curator of the History of Science and Technology Collection and the Film and Media Collection at Stanford University Libraries, discussed the risks of hardware-dependent preservation in 2015:

“Personally…I think hardware-specific solutions are a dead end for preservation. With the type of equipment and hardware we have and the way it’s manufactured, it’s very unlikely that it will survive for a very long time.”
