Blue Archive asset downloader

A small project that downloads all assets of the global version of Blue Archive and extracts them while it's at it.

The script updates the assets and even its own parameters on its own,
so all you have to do is execute the download_assets.py script after every update to get the latest files.

Requirements

• Python 3.6+
• UnityPy 1.7.21
• requests
• xxhash
• pycryptodome
• flatbuffers

Scripts

• download_assets.py
  • This script downloads and extracts the latest assets.
• extract_tables.py
  • Extracts and decrypts the tables from the zip files in Preload\TableBundles
