About This File
A utility program created by zeroKilo (aka Warranty Voider) that allows you to unpack DATA.BIN files from the various .hack PS2 video game discs and ISO's. This tool also allows to repack into DATA.BIN files.
After you've extracted the .CCS files from the .BIN files, you can then view the .CCS files in a program called StudioCCS.
