By using https://github.com/SuperTavor/Viola I managed to unpack the game's .cpk archives.

Now I'm searching for a way to get the models and textures, possibly with their rig intact.

I've found this plugin for Noesis: https://github.com/AFGRocha/Inazuma-Eleven-Victory-Road-Noesis-Script, it was made for the Switch version of the game, but it manages to load some models (.g4md and .g4pkm extensions), but cannot handle textures (.g4tx extension).

I've also seen that apparently the formats are very similar to the one used for Yokai Watch 4, but I haven't found anything that works to be able to load 3d models or textures somewhere.

 

I attached some samples.

IE VR.7z

Little update, .g4pkm may contain bone information. I already included them in the samples uploaded above

Another update, found a janky way to get textures out of the .g4tx files.

If processed with Dragon UnPACKer's HyperRipper, it manages to find the embedded .dds files, which can be exported and opened with Noesis.

It isn't a nice way, but it works.

 

Now all that remains is being able to get rigged models out of .g4md/.g4pkm files.

Found a better way to extract textures.
Kuriimu2 can open .g4tx files and export its content as .nxtch. The exported .nxtch can be simply renamed to .dds and we are good to go.

They changed encryption for cpk

Yeah, it’s still related to the .cpk and the other files from Inazuma Eleven Victory Road. We’re still trying to understand how the new encryption works.

I’m looking into it on my side too, testing different things, checking how it worked in previous games, and searching everywhere I can on forums and technical Discords to see if anyone has figured out the changes yet but nothing for now...

Looking at how the game operates, the models use texture blendshapes

My .. Least liked kind of blendshape.

(Looking at you "Katrielle Layton" 🫠)

Ohwell.

 

Wish I could export my custom chara (easily)
