Unofficial operating system used for the PlayStation hardware, but it's pretty dead and serves no purpose whatsoever.

Disclaimer

This project has nothing to do with PSIO, not anymore. I repeat, this project is not intended for said hardware and shall not be used for whatever purpose connected to it, along with any bits of the sources or the name which I came up with.

PSIO is not affiliated with this at all as the owner of the project is a notorious Australian scammer who's obsessed with money and selling useless hardware (like when he tried building Win98 workstations to be used for PSY-Q, as if you'd really need them). This program died the moment Haunted/Shadow, the scammer, kept being stupid about the open source aspect or the software, which always was open but he has no clue what that means. He doesn't even want you to see this page and censored this link twice on his board, but it's public and all, so feel free to check as it might contain parts of interest, like the zlib+libpng implementation for PNG support on the PlayStation.
