This page is for the first PlayStation system, not the series of consoles. For this, see Sony PlayStation 2, Sony PlayStation 3, Sony PlayStation 4, Sony PlayStation 5, Sony PlayStation Portable, Sony PlayStation Vita, and Sony PlayStation Classic.

Whether these emulators support operating systems for these consoles is unknown; it must be looked into further. Consoles without meaningful OSes are not included.

This device runs an operating system which is known to emulate various devices with EOPs. See the MSX page.

Theoretical, but is an OS on the same architecture as the PS1. Other MIPS OSes are similarly possible, but with varying levels of accessibility and technical info.

to create easy to install 'live' and 'install' cd images of the NetBSD Operating System

This never actually happened for the PS1, and others did the PS2 port. Just a funny oddity that’s one step past being completely theoretical because someone else tried.

Ongoing project to bring Linux back to the sony Playstation 1 [sic]

Based off of RUNIX, but independent enough that it deserves a listing. Reproducing the rootfs memory card is planned, alongside video driver updates.

It didn't output and video from memory, just serial.

Sadly, limited in it’s ability at the moment. Requires a missing tool to correctly build rootfs on mem card. Otherwise works fine, just can’t do graphics or anything cool.

from your PS1: browse the web, send/receive emails, and manage contacts

An adapter cable and suitable i-Mode phone was required for this. Had some cool software.

It supports basic TCP and UDP (untested) communications as well as connecting via DNS

HTTP theorized, but not possible yet.
