I'd like to make Mugen Souls uncensored, since NISA removed the bath house minigame + CGs from the US/EU version.

The game has .CPK files,
CONTENT\GAME.CPK, probably this file contains the needed files.

Is there any tool, or a way to extract & repack a CPK file?
(btw Hyperdimension Neptunia should use the same file, it's also from Compile Heart)
