/* 

Chusan asset extractor for AquaBox URL mode.
    Place your "option" (or "bin/option") and "data" folders in the same directory as this script as they're named.

    Data will be placed into the "chu3" folder.
    Place the contents into a public directory that can be accessed by users.

Know Python or another common scripting language?
    Feel free to rewrite this tool and submit it to MewoLab/AquaDX!
    Or rewrite it in JavaScript again! Anything is better than this hot pile of garbage!
