Reversing the startup sound for the console reveals the developers used a glass-breaking sound. This is most notable with the infamous “Personified Fear” glitch.

Although the PlayStation has extraordinary copy protection, many hackers, home-brewers, and pirates worked around it via the infamous "Disc Swap" trick which is possible as the console uses a lid in a similar fashion to a portable CD player. This trick involves swapping a regular PlayStation disc with a back-up or rewritable CD during the startup.

Likely because of this exploit, Sony created future numbered PlayStation consoles that use disc trays rather than lids.

On the system's Memory Card menu, after deleting data for a game, pressing the four shoulder buttons at the same time will cause the menu to reset and bring back the just-deleted save data. This feature was not carried over to the PlayStation 2.

The iconic start-up sound of the PlayStation is actually a combination of three different clips stored in the system BIOS, which are then either sped up or slowed down to produce what is heard at the boot-up screen. These sounds also serve to check if the system is running normally and is OK to read games - errors within the system can lead to the startup sound becoming distorted.

It is possible in European Demo Discs to change the background of the menu. To do this, you must boot up a demo, wait a few seconds, then take out your current demo disc and replace it with a different one. Then you must wait a few more seconds and press "SELECT" to switch the background. This appears to not be intended as selecting a game not on the new disc will cause it to crash.

The PocketStation was originally going to have a western release, however it was cancelled due to problems meeting the Japanese demand for it.

Marilyn Manson's 9th studio album, The Pale Emperor, was printed on PlayStation discs. Hassan Rahim and Willo Perron, the art directors of The Pale Emperor's disc and case, sourced the CDs from Sony directly. This means that the discs Rahim and Perron worked with, and the discs on which the album was distributed, came from the exact same plant as the PlayStation's discs did.

The buttons on the original playstation controller had a very distinct purpose in their design, according to their designer Teiyu Goto.
The triangle represented a person's viewpoint, meant to look like a head. The square was meant to symbolize a map. The circle and X were meant to represent "yes" and "no" respectively, and it was thought that games released on the Playstation would use controls based on the meaning of these symbols.

The original PlayStation is often mistakenly referred to as PSX, while in reality PSX is a totally different system. It is a Sony digital video recorder with a fully integrated PlayStation 2 and was only released in Japan.

A promotional video for the Sony Playstation appeared on a demo disc for the UK Official Playstation Magazine, known simply as "Elightenment". The video is a parody of Chinese Kung Fu movies with a man seeking to advance to "the higher level" being instructed by and old master about various Playstation peripherals. Very little is known about the video's production and it does not appear to have been shown anywhere outside of demo discs.

The console was originally planned as a CD-Drive add on for the Super Nintendo called the SNES-CD. The plan fell through, resulting in the PlayStation's creation and Nintendo doing a deal with Phillips instead.

In the North American commercials for Playstation, Sony hid multiple subliminal messages. The more obvious was "U R NOT E" - you are not ready (red "E"). Some were cheat codes for games, and another was "E NOS LIVES" meaning "Ready ninth of September", revealing the PS1's release date.
