mhst2-arc-tool

Monster Hunter Stories 2 Arc un- and repacker based on https://github.com/Silvris/MH-Tools-and-Scripts.

Specifically the Extract and Repack python scripts.

Usage

Unpacking

• Drag a packed .arc file from the game folder onto the exe.
  • The tool will automatically recognize that you are trying to unpack something
  • Inside the unpacked folder there will be an orderlog.txt, do not delete it, you will need it to repack the arc!
  • It will also generate an [arc name]-decrypt.arc, which you can delete after unpacking is done.

Repacking

• Drag an unpacked arc folder onto the exe.
  • The folder needs to have an orderlog.txt inside that lists all of the arcs files.
  • Output will be [folder name]-repacked.arc

Building

Used libraries can be installed either manually or with vcpkg.

vcpkg

$ vcpkg install zlib cryptopp boost-crc --triplet=x64-windows-static

There is an option to enable progress bars (which massively slows down the code). The libraries for that can be installed with

$ vcpkg install indicators fmt --triplet=x64-windows-static

You can omit the -static if you wish to use the libraries in dll form.

Then simply open the solution is Visual Studio, make sure to select x64 as the target, and build.
