VITA :: *.CPK EXTRACT

Post by bam_bam »

Hi, I know there is a cpk.bms. But it doesn't work my game file.
I've tried for several times with another cpk tool, unfortunately I've all failed.
The title of game is Nekketsu Inou Bukatsutan trigger kiss.
I would appreciate it if you could help me. Thanks.

If my cpk.bms script doesn't work then I have no solutions.

I highly suggest you to provide filecutted samples when the file are so big (2.4Gb) or there is the risk that many people will not even check it.

Hello, Luigi!

Your cpk.bms works fine with Odin2_RE_US.CPK - one of Odin Sphere: Leifthrasir archives. But fails on other two. May be problem in TOC parsing: first filename looks cutted. Can you look?

cpk files are no longer supported because the offset of the files is not clear.
In this case it looks like the offset is 0x800 byte more than the calculated one.
