Hi, I found that 0x4 means Get files long. But I don't know how to unpack these files.

I guess the 8 bytes of information of the files (probably size or offset size or zsize size) and the files are encrypted with blowfish (ecb) but I have no idea about the key (it's not the bytes in key.dat).

I found how to unpack *.int files. http://asmodean.reverse.net/pages/exkifint.html
Could you make bms script?


unpack sample https://www.sendspace.com/file/zkloia
*.int samples https://www.sendspace.com/file/48z1v4

exkifint_v3_unpack.bat will unpack *.int files. Unpacked files use zlib.
For example, ama_002b.cst file from scene.int...

Code:

idstring "CatScene"

for
get ZSIZE long
get SIZE long
savepos OFFSET

get packname filename
   string packname  = _unpacked/

clog packname OFFSET ZSIZE SIZE

savepos OFFSET

if OFFSET == EOF
clenexit

next

Result


exkifint_v3.exe will find in Grisaia.exe.
All *.int files can be unpacked exkifint_v2.exe with FW-XGHSGKCJ.
But it can't get name and extention, so exkifint_v3 is useful.

The files are dumped without filename because it's game specific, but now you can reimport them.
CatScene files are decompressed on-the-fly.
