Cethleann - The Koei Swiss Army Knife

[Yretenai]

Over the last couple of months I've been working on a bunch of open-source tools to extract and work with various Koei Tecmo games such as Fire Emblem: Three Houses and Dissidia Final Fantasy NT Free Edition (Steam.) It has tools for uncompressing files, virtual FS containers (FETH's DATA0/DATA1, Atelier PAKs) and unwrapping concatinated files (.bin, .gmpk, .mdlk)

The main tool to use is Cethleann.Unbundler, this tool will take most concatinated files and output individual files. It has support for FETH SCENE, MDLK, KTSR, KTSC, LX19, GMPK, GAPK, G1L, KOVS, and RTRPK files.

This has ZERO SUPPORT for Big Endian files.

Builds: https://ci.appveyor.com/project/yretena ... /artifacts
This project REQUIRES .NET Core 3.1 Runtime (x64.) Download here

Click on the latest build and download the Cethleann-Standalone artifact.
Atelier support is experimental, "should work."
Gust elixir.gz support coming soon.
Support for Nioh VFS is coming soon.

This tool is created in tandem with Joschka's Noesis fmt_g1m plugin.

Special Thanks To:
- id-daemon's Dissidia model converter which gave me reference data to test again
- HeartHeroDE's th-hack-tools whose implementation helped me understand STRUCT formats
- The Fire Emblem Three Houses Datamining Community for creating binary templates
- Ploaj's Metanoia whose implementatino helped me understand G1Ms
- Quickbms' arslan.bms for having a LINKDATA implementation to base off
- VitaSmith's gust_tools whose implementation helped me understand Gust PAKs and textures
- Eternity's rdbtool for helping me understand animatinos, RDBs, RDB hashing algorithms, and the DoA6 file list
- chrrox for helping me understand RDBs and figuring out what compression algorithm the switch uses.


Latest Version: 1.0.58
Changes: here

I only have one conclusion going down this journey:

[Darkhowlings]

Weird, one of the links gives 404 error on github...

Anyway, will love to try, but, I kind suck to build stuff from github.

Ah, I forgot it requires a GitHub account to view the builds. I linked a direct link which should work.
Sorting out a different build solution.

Builds are now on AppVeyor, which should be public for all

Tried it with Attack on Titan 2, but ye

Unhandled exception. System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')
at DragonLib.CLI.CommandLineFlags.ParseFlags[T](Action`1 printHelp, String[] arguments)
at Koei.DataExporter.Program.Main(String[] args)

but then noticed that LINKDATA isn't supported yet lmao

Yeah LINKDATA support is soon, I mostly started this for Fire Emblem 3 Houses, Atelier, and Dissidia NT

Edit: Added LINKDATA support, check the AppVeyor build artifacts for a new build.
Please tell me if it works, I'm not 100% on it working.
Please note that I haven't tested this but it should work.

Alright, I'll test it soon.

nadda


dunno if the file setup has to be proper...

oops, fixed

[Yretenai]

oops, fixed

Fixed!

Added a new tool: Omega.DataExtractor.exe-- Usage:

Code: Select all

Omega.DataExtractor.exe --game AttackOnTitan2 C:\AOT2 "C:\RomFS\Linkdata"

In your case it would be:

Code: Select all

Omega.DataExtractor.exe --game AttackOnTitan2 F:\HACTool\AoT2FinalBattle\secure\romfs\Linkdata F:\HACTool\AoT2FinalBattle\secure\romfs\Linkdata

It will create a new folder for each LINKDATA bin.

Models are wrapped in a container, will add support for that tomorrow.

[demonslayerx8]

Alright cool, I'll wait til the container support is added~

[Yretenai]

Alright cool, I'll wait til the container support is added~

Wrapped files are now supported.
Keep in mind that AOT2 has no filenames, so you just have to do the tried and tested method of unwrapping every file.
Use Cethleann.Unbundler.exe to unwrap them, or pass --recursive to Omega.DataExporter.exe's command line options

Models and textures tend to be in ptrbundle files.

what am I doing wrong?

[Yretenai]

what am I doing wrong?

Nothing, there was a bug.
I just fixed it. Appveyor should have a fixed build in 5 mins.

[Yretenai]

I just fixed it. Appveyor should have a fixed build in 5 mins.

Ugh, AOT2's file bundle code is crashing. It's fixed in the new build. (Give appveyor another 5 minutes)

Sorry that it's crashing so much.
