Some scripts I had to create in order to analyze Bayonetta file structure.
You will need some packages especially for the importer.
sudo apt install ruby ruby-dev git build-essential zlib1g-dev libassimp-dev imagemagick
You will need the nokogiri, libbin and assimp-ffi gems installed.
gem install --user-install nokogiri libbin assimp-ffi
Additional gem may be needed for some tools, like zstd-ruby for Astral Chain archive decompression.
