Tools for *packing, *crypting and editing various Monster Hunter Frontier Online files.

Repo made public as of 07/17/2019 on occasion of the game in question being shutdown in December 2019. Tool was intended for personal use only, so it might be a bit messy to foreign eyes. You're likely looking for ReFrontier itself and can safely ignore the other tools.

Huge thank you to enler for their help!

ReFrontier options:

Unpacking Options:
-log: Write log file (required for repacking)
-cleanUp: Delete simple archives after unpacking
-stageContainer: Unpack file as stage-specific container (for certain stXXX.pac files and maybe others)
-autoStage: Automatically attempt to unpack containers that might be stage-specific (this is very experimental, since there is no reliable way to detect a stage-specific container)
-nonRecursive: Do not unpack recursively (useful for modifying specific files in archives, also check -noDecryption/-ignoreJPK)
-decryptOnly: Decrypt ecd files without unpacking
-noDecryption: Don't decrypt ecd files, no unpacking
-ignoreJPK: Do not decompress JPK files

Packing Options:
-pack: Repack directory (requires log file  - double check file extensions therein and make sure you account for encryption, compression)
-compress [type],[level]: Pack file with jpk [type] at compression [level] (example: -compress 3,10)
-encrypt: Encrypt input file with ecd algorithm

General Options:
-close: Close window after finishing process

Project license

I noticed the project is unlicensed. Do you plan to release it under an open source license?

Some helpful information from the GitHub Docs: Licensing a repository

We created choosealicense.com, to help you understand how to license your code. A software license tells others what they can and can't do with your source code, so it's important to make an informed decision.

You're under no obligation to choose a license. However, without a license, the default copyright laws apply, meaning that you retain all rights to your source code and no one may reproduce, distribute, or create derivative works from your work.

Got this issue when trying to encrypt music

sup

got this error :
System.IndexOutOfRangeException:
LibReFrontier.Crypto.LoadUInt32BE(Byte[] buffer, Int32 offset)
LibReFrontier.Crypto.getRndEcd(Int32 index, UInt32& rnd)
LibReFrontier.Crypto.encEcd(Byte[] buffer, Byte[] bufferMeta)
ReFrontier.Program.Main(String[] args)

i suppose this is not normal.

there is another way to reencrypt music ?

How could i use this to dump monster icons?

I maintain a spreadsheet that lists/categorizes every monster from the MH series. I recently managed to finally dump the spritesheets from MH1, MHF, MH2, MHF2 and MHFU which i couldn't find in their original resolution anywhere online.

But now the only icons that are missing are all the ones from Frontier. I have the game files (from fist.moe) but can't figure out how to use this tool for my purpose. I previously tried a tool i found that was made for MHFU/MHP3rd but that doesn't work on the Frontier files.

How to unpack ecd files

I want to do a Spanish translation for MHF and I really don't know how to unzip the .bin files (ecd I think?) with this program.

I tried to put different lines in the console but this just closed it.

I know practically nothing about decrypting files and if you can help me I would appreciate it.

How to use? (Beginner)

I'm so sorry but I'm new in using source code. Been looking for a whole day how to use Github code but I understand nothing. Did try using Visual Code but also have zero experience and broke it, now my SDK is unrepairable and cannot be detected even after installing all version to 4.0 to 7.0 (+all type of C++/C# extension).

I just wants to extract the monster.pac files for 3D
any help?
