What is ps-pkg-server?

PS PKG Server is a simple HTTP server for self hosting PS4 and PS5 game package files, known as PKG files, so you can serve them to your own consoles over your local network. Rather than relying on file names, it reads the metadata stored inside each package to identify its contents. If a package has been split into multiple parts, the server serves it back as one continuous file, so the console sees a single download. It can also identify fpkg update files that are not tied to a specific base game package, and it supports pushing packages directly to consoles running a companion project called ps5-ezremote-dpi, or similar remote installation services. You can run the server through Docker using the included docker-compose.yml file, or run it directly on your own machine. Running it on bare metal means installing Python dependencies from a requirements file and starting it with uvicorn, a Python web server, pointing it at a folder of your PKG files with an environment variable. Once it is running, you open a web page on localhost to browse and manage the library. A handful of settings control how the server behaves. You can set which host path holds your PKG library, which directories inside the server it should scan, how many files it parses in parallel, and whether to force a specific host and port for downloads instead of letting the server detect it automatically. Icons and other data the server generates while running are saved to a separate folder so they persist between restarts. You can also add more than one PKG library by mounting extra folders and listing them together in the directory setting. The README credits three other open source projects for reference material on the PS4 and PS5 package file formats and the update marriage checksum method, which this project relies on to understand how the files are structured.
