CVM is an archive format used in the PS2 versions of Yakuza and Yakuza 2. It was developed by CRI Middleware and based on ISO9660. It is also known internally as "ROFS" format. Essentially, they are ISO files with a special header (0x1800 bytes).
List of games using
The games listed use .CVM files:
Modify
In order to extract CVM archives, you will need cvm_tool.
Ryu Ga Gotoku: Kenzan! and Yakuza: Dead Souls use CVM for Auth audio. They are not encrypted.
To split/create any CVM from either game, the command would be:
cvm_tool.exe split FILENAME.CVM FILENAME.iso FILENAME.hdr
cvm_tool.exe mkcvm FILENAME.CVM FILENAME.iso FILENAME.hdr
For Yakuza and Yakuza 2 (PS2), they are encrypted.
To split OGRE.CVM from Yakuza, an example command would be:
cvm_tool.exe -p qi2o@9a! split OGRE.CVM OGRE.iso OGRE.hdr
To create a cvm out of OGRE.ISO into OGRE.CVM, the command would be:cvm_tool.exe -p qi2o@9a! mkcvm OGRE.CVM OGRE.iso OGRE.hdr
