CLS

CLS stands for Content Licensing Server. It is likely what Nintendo uses to store DS, DSiWare, Wii and WiiWare titles and to license them.

In the leaked data from the Zammis Clark Breach, more specifically emeralds.7z and wiidump.7z, there have been references to a directory located somewhere on Nintendo's servers, called "CLSs", or "CLS". This supposedly contains a copy of every DS and Wii title ever, organized into neat little folders, with a production partition and a development partition for each title. The folder is also a CVS repository.

It is unknown whether Zammis Clark or his friends had ever dumped the folder in its entirety or not, but there is data from the folder that has been leaked.

In the root directory of emeralds.7z, the leaker placed four 7-zip archives/folders that contain Wii titles:

• BOOT-DIAG
• RVL-FFWP
• RVL-RAAE
• RVL-WTester

The extracted contents of each folder all follow a very similar format in the way they are organized. They are all checked out from a CVS repository named "CLSs", meaning they all used to be subfolders of the massive CLS folder.

Since FFWP (Donkey Kong: Original Edition) is a Virtual Console title, it could be possible that this CLS folder does also contain Virtual Console and WiiWare games, maybe even retail games, and not just development discs and repair discs.

Example filesystem

The contents of CLS are usually organized in the following format:

• 🗁 CLS / CLSs (the big folder)
  • 🗁 Title name (Usually the console's product code followed by the title's GameID. For example, if this were the Startup Disc, RVL-RAAE would be the name of the folder)
    • 🗁 Version number (Starts at v0. Most titles don't have multiple versions, so v0 is usually the only subfolder. Sometimes, there can be more than one, like "v1" or "v256")
      • 🗀 CVS (only present sometimes)
      • 🖹 product code + - + GameID + -v + version number + .cls
      • 🖹 product code + - + GameID + -v + version number + .prod_part
    • 🗀 CVS (only present sometimes)
    • 🖹 properties (literally just a file named "properties" with no file extension. contains information about the title)

CVS folder

CVS is a folder left over after being checked out from a CVS repository. Can contain interesting info, like names of parent directories.

• 🗁 CVS
  • 🖹 Entries (auto-generated commit log. sometimes has annoying copies, like "Entries.Old", "Entries.Extra", "Entries.Extra.Old", etc)
  • 🖹 Repository (contains the name of the parent directory of the parent directory, as plaintext)
  • 🖹 Root (contains the full path to the folder, usually starting from the root directory of the drive)
