GFXCrunch misinterpreting data as AT4PX

[Techokami]

Hello!
I just cloned and built this repository on my Fedora Linux machine, and I'm having some trouble with getting GFXCrunch to do what it is supposed to do. When I feed it the "m_ground.bin", "m_attack.bin", or "monster.bin" files from EoT, it claims it is AT4PX compressed and stops.

techokami@markv:~/GITS/ppmdu_2/ppmdu_gfxcrunch/bin$ ./ppmdu_gfxcrunch ~/Unzipped/NDSFactory/PMDTime/MONSTER/m_attack.bin

== Baz the Poochyena's PMD:EoS/T/D GfxCrunch - 0.13.0 ==
========================================================
A utility to unpack and re-pack pmd2 sprite!

"m_attack.bin" wants to battle!
Poochyena can't wait to begin!


Welp.. Poochyena almost choked while crunching the pixels!

Exception : Raw AT4PX compressed files not supported at this time!

I used PackFileUtil as a sanity check, and it spat out files that it claimed were AT4PX compressed, but looking inside, I actually was finding the uncompressed art data I was expecting. This is rather peculiar! Any idea what exactly is going on?

Note: I should mention that my ultimate goal is to use these tools with files from a different Nintendo DS Mystery Dungeon game, but they have very similar data formats, especially after comparing what I was seeing in the files extracted from m_ground.bin (the only real difference is the use of a global palette rather than embedding palettes into each file).

Hi! Sorry for the late reply. I don't know if you still need help with this, but I did find some problems in the code.
I'm surprised it's detecting the file as a AT4PX file, since packfiles start with 4 zeros and at4px starts with at4px..
Also, I did build and test it locally and it seems to tell the file type properly.
There's definitely something weird going on there though. And it's definitely possible there's a bug on my end. It's been behaving a bit weird.

Idk if you can run wine or something like that to run the compiled executable of the old version of gfxcrunch? : https://github.com/PsyCommando/ppmdu/releases/tag/ppmd_GfxCrunch_0.13a
Because, that could be a faster way of getting those sprite files extracted. With that said, I don't know if it'll work with a global palette.
