ijji/korean Gunz Client Unpacker and Decrypter

Hello,

I am releasing some binaries and batch script that will decompress and decrypt the Gunz Client from ijji gunz or korea gunz.

How to use:
1- Download the package I released
2- Extract the package in a folder.
3- Copy all the Gunz MRS files, including the folders that contain MRS files to the client folder included in this package.
An example of the selection you have to copy is:

Interface
Maps
Model
Quest
Sound
model.mrs
sfx.mrs
system.mrs
Update1.mrs
Update2.mrs
Update3.mrs

4- Run the unpack.bat script.

The unpack.bat script will take ALL the MRS files inside the ./client folder, then it will decompress them and after it decompressed them, it will decript all MEF files using the latest MEF private key from MAIET. After that it will move the update files to the standard folders.

You may get some warning messages when decompressing, ignore them.

All binaries are built from gunz source code, except the pkzip.

Download Link: Multiupload.com - upload your files to multiple file hosting sites!

Enjoy.

Niiiice man!

Thanks man u make all easier tyvm.

Very nice.

so, how to make it back mrs?

use tool pack to mrs, after use MEncrypt to encrypt with publickey.txt?

your step:
1. convert mrs > zip
2. unzip
3. decrypt .mef

so, after finish modify, we need do:
1. encrypt .mef
2. zip
3. convert zip > mrs

so how to convert zip to mrs :D

wait what does this do? :D does it turn english version of gunz into korean? *hopes so* :D?!?!

IJJI changed their files and encrypted them, normal MRS Decompilers won't work, but this awesome release will do the trick.

Use MAIET's convzip tool, it's in the Utils part.

okay i got something weird.
in my eyes.

i tryed it with delpa's emulator (just to look out the items)
and i used it no problems at all
put all the xml's inside the system.mrs to the server files.
but it crashes when it loads the xml files.
wich i had no problems with with the xmls inside the client delpa used.

i am also always just puttin in all the xml's always worked for me without issue's

any things i should have change.

I think that client uses the old private key.
You can get the old private key at the posted gunz source.
Just put that private key at the privatekey.txt of my package.
