Screenshots from Disc 1

Screenshots from Disc 2



  • There are currently no videos for this game.




  • Despite having the same name, the Disc 2 Squaresoft PlayStation Previews shows more content than the stand alone disc version.
  • This issue focuses on Final Fantasy VII, which was developed by Squaresoft. Almost every programmer’s cheat involves using the Square Button.
  • In the secret Game Tester screenshot (See Secrets Tab) you can see the Debugging PlayStation on the counter.
  • If you watch the director’s clipboard animation, the changing numbers eventually read ENOS. That was part of Sony’s original marketing campaign – ENOS (with a red ‘E’) was short for “Ready, Ninth of September.” It was also Sony written phonetically backwards.



Carrying on the traditions of the original release, PlayStation Underground 1.2 has areas where inputting secret commands gives you more content.
