Sonic and the Secret Rings [Wii]

There are .one archives in this game, which are well documented. I extracted them using this tool: https://github.com/nickworonekin/puyotools, which gave me the expected model and animation files (see examples.zip). I imported these using this Blender add-on: https://github.com/Argx2121/Sega_NN_tools.

However, there are also extensionless files in the "Now" folder, such as those in the attached samples.zip file. They appear to be a different type of compressed archive, and I do not recognize the compression type. This is as far as I got for a basic ImHex template. I would appreciate any insight into how the data is compressed.

    Asset asset @ asset_off;

struct File {

    le u32 asset_count;
    u32;
    AssetPtr assets[asset_count];
};
