Infamous Cri Middleware proprietary format. Used in numerous console games for PS2, PS3, PS4, PSP, PSV, Xbox 360, Xbox One, 3DS, WiiU and even PC.

This format is not static, recent titles have a bit different format, but usually it have support of all older containers, so it is possible to recreate the files using leaked CRI File System tools 1.36.

So only trick part is to extract the files. Through the years were created lot of tools, but I will include only two:

BMS script is a bit dated, but still working, but generally better use CriPakTools. There is also possibility to re-insert the blocks back, without need of repack, if the file is not bigger than initial file.
