    • The disc has a laundry list of programmer’s cheats that gamers could write down and then use once the game was swapped in. It should be noted Sony shortened the game names to fit in the confined list graphic, so we have kept them in their original order below. For example, Battle Arena Toshinden was just ‘Toshinden’, hence why it is in the T area and not B.

Screenshots from Disc 2



  • There are currently no videos for this game.




  • The PlayStation Underground had a nifty gimmick when it came to hidden content. In this original issue, they flat out tell you you’ll need to find various hidden goodies via programmer’s cheats. They just don’t tell you what those button inputs are.In Volume 2, they gave away all the secret inputs and material it uncovered. This tradition of showing you what the previous issue’s secrets were would become a running gimmick in the series.
  • If you press Start when in the menu selection screen, the option to turn off the music pops up. Press Select to go back.




The first Underground disc set has 2 hidden music videos, a hidden Blasto teaser video, and even a character of a then Sony employee. Here are the locations and button commands you’ll need to see everything.
