Thanks for the update. Adding the Bakin support is great news. Having consistent directories is also nice.

Got my hopes up with the Bakin support and tried it on two games.

Yeah, I've asked for games to test with, and all I got was this one (which is fine, just nowhere near enough samples).

It didn't work for tested games, but I found out that

got an update recently and it worked.

I've compared my implementation with that one (I mean with the latest) to verify. Should be the same.

Providing game downloads and info below.

Thank you very much, they are downloading now, I'll take a look!

Crash.
corrupted archive, resource offset @36237b16 does not match zip end @0004015a

That's not a crash, but a proper error message. And it seems to be valid, I'll take a closer look once the sample game has downloaded.

Only Info tab is available

This means no image assets were found (either because there's none, or they are using some obscure format). I'll look into this too.

Hope this helps. Please let me know if you need anything else.

Thank you so much! Example games that I can test with was what I needed the most.

The latest BakinExtractor worked on both games.

Except it most certainly does not. Pink light has 1.0 as pak version and yet there's an additional byte in the header (which BakinExtractor only considers if pak version would be 1.1, but it's not). I've added some heuristics for this.

Pink Light didn't get exported into plain pngs though, exported files required KastViewer from release of BakinExtractor

Except it most certainly does not. KastViewer uses an invalid header size for version 1.0 and incorrectly identifies the pixel formats (see

). It does not support 1.1 at all.

From the limited samples I have, I've reverse engineered the .kast files, the XETK 1.0 format (all, except one pixel format is working). I've tested it with your game, but I've also downloaded the test games from Bakin's website. It turned out that XETK already has an (of course incompatible) 1.1 variant... Nevermind, I've added support for that as well. It seems there's no new pixel format code, just a different header size.

I'm still not 100% sure if I got all format/flags/RGB-BGR combinations correctly, but seems okay with Pink light, BakinDRPGSample_en, BakinSample_en, Holehole and Embarrassed Shina-chan. One pixel format (format = 0x0A, unknown3 = 2, flags = 1/1/1 combination) is known to be using BC3 decoder while it should not.

Could you please give a try to this version?

That's not a crash, but a proper error message. And it seems to be valid, I'll take a closer look once the sample game has downloaded.

App suddenly closed with no message, so it seemed like a crash, with error message only being displayed in the log file (if logs are enabled).

Actually, so far I couldn't find any .kast images in Pink light that KastViewer could display at all, so any help would be appreciated.

Not sure if it helps, but here's what I got (from the point of software user).

I was unable to find any doc on this format either, what I could figure out is as follows:

Thank you for looking into this.

So I narrowed down kast files to 4 image textures (by removing other kast files), and extracted them.
Here's a zip with 4 kast files, file path list (kast path, image path), and extracted images (placed them in the same folder as kast file)
Again, no idea if that helps, but that's what I could think of here.

Thanks, but you're a bit late.

GR already supports .kast images, and lot more variant than KastViewer (it's not just KastViewer misidentifies lots of variants, it does not support 1.1 while GR does).


EDIT: okay, I got the last piece in place (turned out I miscalculated one of the header fields offsets, fixed). Now all pixel format variants work perfectly, please check out this latest GR version!
