The PSX has an updatable firmware. Updates could be performed through an online service that has since been discontinued, or - alternatively - via update discs that were available free of charge via mail order directly from Sony Japan until early 2014.

The first generation PSX (DESR-5000/7000/5100/7100) consoles run a different/incompatible firmware (ver. 1.xx) than the second generation PSX (DESR-5500/7500/5700/7700) (ver. 2.xx).
For further details and changelogs, see PSX Firmware changelog.
