[help plz] WarioWare Get It Together - Ripping In-Game 3D Models (and other stuff?)

[Dark 9-Volt]

This is my first time on this board, so i will try my best to explain this quickly.

I had the idea of ripping in-game stuff from the latest WarioWare game: "WarioWare: Get It Together!" from Nintendo Switch.

This is what i've done:

-I dumped all the "romFS" files using the Yuzu emulator.
(includes: Introduction scenes, audio files in opus format, etc...)

-I extracted character files (e.g. 9-Volt.) which includes 3D models and textures using the "Switch-Toolbox" program.
(Character files are in the "Archive" folder, all of them are in .bea format, which can be opened with said program.)

And now, which where am i right now: I converted a 3D model to a .dea file so can be opened with Blender and stuff, but...
i don't know how to use Blender. (One of my issues being that i'm trying to rotate the head.)

Here's a Drive folder i've did which contains ALL of the stuff i've extracted from 9-Volt's .bea file.

Can someone help me out with all of this? (Mostly, the Blender part.)
