WorldChunkTool

Tool to decompress and extract Monster Hunter: World and Monster Hunter World: Iceborne chunk*.bin files.

==============================
WorldChunkTool v1.2 by MHVuze
==============================
Usage: WorldChunkTool <chunk*_file|PKG_file|chunk*_dir> (options)

Options:
        -UnpackAll: Unpack all chunk*.bin files in the provided directory into a single folder.
        -AutoConfirm: No confirmations required. (-UnpackAll uses own confirmation settings.)
        -BuildPKG: Build PKG file from chunks and create data sheet. No extraction. For research purposes only.
        -BaseGame: Switch to legacy mode for MH:W base game chunks (pre-IB update).

oo2core_8_win64.dll required. Monster Hunter World: Iceborne DOES NOT ship with this file. oo2core_5_win64.dll from the base game is outdated and won't work! You can find the new DLL in recent games like Warframe (F2P) and STAR WARS Jedi: Fallen Order. Simply search for it in the game installation directory and copy it to the same folder as the WorldChunkTool executable.

WARNING: Please be careful and don't download oo2core_8_win64.dll randomly from the web.
