Ninja Warriors Once Again and Dark Judgement Sprites?

[DogToon64]

Downloaded Yuzu and the "Yuzu Files" (no idea what they are, but it just works) and opened the ROM with it. Then I extracted the romfs and saw that it this game was made with Unity, so I opened it with AssetStudio (formerly UnityStudio) and got this:

I have access to the files, but somehow I can't see their contents.
Since I'm very new to this kind of ripping, I don't really have an idea on how to progress from here.

I'll read some tutorials and maybe something will come out of it (or not).

If you go to "Asset List", then you'll be able to see it's contents.
