SourceIcon.png This game has uncompiled source code.
GraphicsIcon.png This game has unused graphics.

To do:
Check all of the remaining Jampacks as well.
  1. Double check the unused graphics! Most of these were gotten from the Mature version. Perhaps the Teen version has a few more unused stuff.

Jampack was the title used for a series of PlayStation and PlayStation 2 demo discs released in the United States from 1997-2006.

Dummy Files

Winter 2002

Jampack Winter 2002 Teen has a DMMY file in the root directory which is a debug enabled version of Dark Cloud. This can be played by using the retail USA version's files of Dark Cloud and replacing the executable SCUS_971.11 with the DMMY file after renaming it to the same name as the executable. Additionally, the SLY folder contains a backup of the executable for the Sly Cooper and the Thievius Raccoonus demo named SLYELF~1.CD. It does not appear to be much different, as the file size matches with the intended executable and it is dated the same day as the other files in the folder.

Unused Graphics

A placeholder control screen for Tomba!. Unlike other games in The Vault, Tomba! has the control scheme graphics built into the game's demo files.

Volume 10

Jampack10-MENU sly2 control0.png

Placeholder graphics. The Missing Control Screen graphic is named sly2_control0 as Sly 2 only had viewable trailers and no playable demo.

Volume 11

Jampack11 MENU-menu res-icn13.pngJampack11 MENU-menu res-icnM.png
Unused boot sequence graphics.
Similar graphics were used in Volume 10, where the red one represented the Teen variant and the yellow one - Mature. Volume 11 on the other hand skips the boot sequence\animation making these graphics go unused.

Placeholder graphics, identical to the ones found in Volume 10.

Volume 12

Jampack12 MENU-menu res-pub-projects-jampack12-sprites-volume12.png
