Hi, I'm having problems trying to extract Storm Lover 2nd's images.

I manage to extract the contents of the game's union.cpk file and here I hit a road block.

All images were stored inside .bin files, but they have no header. To make matters worse, some have a different beginning hex values (Some files start with 0xC8 0xC3 0x01 0x00, while others start with a random 0x values, followed by 3 0x00). 

Here some of the .bin files. Any help to extract the game's images would be appreciated.

SL2bin.rar

The first 2, is gzip compression, you can open it with winrar.

I opened the files with Noesis's TextureFinder tool and it gave me no result.

Changing width, offset and format didn't work so it seem like these images were compressed.

Not compressed but the images was swizzled.
With these parameters in Kuriimu2, I was able to decode the images.


*The height was wrong actually. It's should be 512.

While using Kuriimu2 gave me some UI assets, I have no luck with CG and sprites assets.

Luckily, using AnimeED's raw image tool gave me some results.

The problem is the palette offset. I have no idea where the offset is.

Below are rar file contains sample CG and sprites.

 

SL2SampleCGSp.rar

You won't find any palette datas because your sample lacks it.

That viewer is not in our texture viewer/finder list (https://reshax.com/topic/170-graphicstexture-finders-and-viewers/), and I'm not finding any active links to it 🤔 (just this nearly empty match https://github.com/AnimeEd). Do you have a link to it? TY.

Actually, it is compressed, the first file he uploaded uses gzip compression, you just can see the images in kurimii2 if you decompressed it.

Not compressed, you just look in wrong way.

No palette so far. I'm starting to think there are some image formats inside the uncompressed file (TGA? DDS?).

@Rabatini Hi! I'm curious, which of the files is compressed with gzip? None of the files seem to have a valid GZ header. When you say 'the first 2', do you mean 01 00 00 00.bin and 02 00 00 00.bin?

Yes.

Actually this 2 files are containers with bunch of gzip compressed images.
so, you cant just uses winwar, because it will just decompress the first image.

in 2.bin have 15 gzip files.

contain images.

I made a simple script in python, to unpack all gzip files from the bin, you can downloaded.

Thank you, the script works really great! On an urelated note, it's also work with Bad Apple Wars (PSV).

Still no palette data of CG and sprites.

Here's unextracted .bin files that contained CG and sprites, maybe there are seperated palette data inside these files?

SL2CGbin.rar

Is this the right pallet?

Yes, it is. It's there a seperated palette files?

The pallet is inside .bin file at offset 0x90
and the order to read is bgra

from other file, chooice the bin file, and put these configs.
