New GIGA encryption? "Data not recognized as zlib-compressed stream"

[Veshurik]

Hello, I noticed that interesting things - all new GIGA releases starting "Ai Kiss" doesn't open in GARBro, because Data not recognized as zlib-compressed stream.

It can be opened with Data Extract v. 1.20, but with random order and other names, not with names as original archives.

Maybe, you know how to fix it? Thanks.

@Veshurik Data Extract v. 1.20 ? What is that?

[Veshurik]

It's extractor program, you can download it. Extract Data English v.1.20

[Ryona-Fang]

Extract Data English v.1.20

Can you please be more specific ? I tried searching it on google but all that comes out is gibberish.

[GaryTheSavage]

@Ryona-Fang I managed to find one on this website. https://vnerogereview.wordpress.com/otakus-toolbox/ In an archive with a bunch of other tools. And it actually worked.

PS: I just analyzed Ai Kiss...

Ai Kiss has an unknown compression type "0x07", but it is indeed raw data without any processing, just like "Compression.None". So the only thing we need to do is adding this value into the code.

Bgm.arc

Can you please explain more? Right now I'm trying with "Full Kiss S", but don't understand what to do. I open .PAC file with Notepad++, and it writes PAC at the start.

The new version just change header of file ( PAC\0 -> PAC\x7F, mode=4 -> mode=7 ). And use zstd to compress file.

NeXAS_Unpack.zip

I know I'm too late, but I have a question. Can I repack .pac? I want make nude patch, but don't know how to repack. GARbro doesn't support pac repack.

[JoGaTo]

So will the NeXAS_Unpack thing will unpack the latest AiKiss game that came out a couple of days ago? GARbro can't extract anything from the new game because of "Data not recognized as zlib-compressed stream" but was able to extract images from ExtractData, Crass, and exchpac, however cannot extract config.pac from any of them, and I need that for one of the files inside as that file is needed to merge the images using tools from exchpac.

EDIT: Nevermind, just tried it. It works.

[Veshurik]

Yep, it works perfectly, thanks to author of this program. This is version with manual, if someone don't understand how to use it. GIGA Extract.zip

Thank you very much! Hm... I'm trying it, and still program crashes (drag and drop .arc file on .exe with unpack). What am I doing wrong? Uhm, the problem was in folder file name with "／" symbol. Now it works...

Hello again. I have a new problem with Senkou no Clarias F - Grimm o Tsumugishi Mono game. When I drag Update.pac on the .exe program, it crashes. But Update2.pac works okay. Is it because of the size of archive? Can anyone help, what to do? Thanks!

Man, thank you very much!!!

Finally I check pac_unpack's code.
struct index { uint8 name[64]; uint32 Offset; uint32 FileSize; uint32 ComSize; }Index[7000]; // This is max file count.
https://github.com/AyamiKaze/Niflheim/blob/d8123c815e34386a3998bb119de61dd59f3421bc/NeXAS/BALDR_HEART/pac_unpack/pac_unpack.c#L33 For unpack pac whtich have file count over 7000, just change 7000 to the max file count. For example :file count is 7100, change 7000 to 7100.
For pack pac, it's sam as unpack.
