LOL.... Thanks to @

lastfun ​

for your hard work in great C# project.
sysstring.ini is unpacked.... LOL

@lastfun​

Do you have any solution to unpack .package files?

Thank you. That's awesome.

 

[Hycker]

.package files? Last time when i meet with that extensions (saiyuki) its a XORed plaintext files copy *.* > file.package format with specific header 32bytes.

.package files

??
in this game?

p.s. maybe someone useful
unpacks all the files in the current folder, the extracted files are stored in Unpack folders

[AnthonyX]

Oh my mistake on saiyuki...
This game don't need .package file unpacker.
Just .dat, .png and .ini unpacker for this game. LOL

 

[Hycker]

U can unpack unxor xor repack files in Saiyuki but its does not matter coz the file checking on the executeable destroy the game if there is modification in the .package files... I tried like 1month to avoid this w/o luck... But that is an another story

This game has a tool for .dat builder from excel. Great news.

if we say that "saiyuki" = "ZYJ\ZuOnline\Client.exe"
I just watched it (Client.exe).... *.package
it compares (100%) the file creation time to time file changes - if they are different -> the client has broken...
for example - take any package, open in hex editor, save - try run client -> crash)
take this package, mod datatime in (for example) -

(Created Data = Modifier Data), try run client -> OK)))
perhaps, there any check...

 

[lastfun]

small update
ZuOnline client without checking (need test) -

about crypt datapack....
Validate.dat crypt simple XOR in several passes (key = "0.0.0.1")

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace ZU
{
    class Program
    {
        static void Main(string[] args)
        {
            var input = File.ReadAllBytes(@"Validate.dat");
            byte[] key = { 0x30, 0x2E, 0x30, 0x2E, 0x30, 0x2E, 0x31};
            for (int x = 0; x <= key.Length-1; x++)
            {
                for (int i = 0; i < input.Length; i++)
                {
                    input[i] = (byte)(key[x] ^ input[i]);
                }
            }
            File.WriteAllBytes("Validate.dat.unp", input);


            Console.ReadLine();
        }
    }
}

result:

....
now i look *.package (to be continued))) )
---upd---
*.package - is not a difficult structure, at the moment i'm writing unpackers for *.package )

 

[AnthonyX]

Thank you I hope to see the unpacker for *.package files.
That's the hard work. I don't know how you can do that LOL

@AnthonyX Pick me on skype and i give ya all tools for that

I freeze work for 3-4 days
1. there is no make sense to do this, if you already have
2. all the files at work (3 days holiday)

 

[Hycker]

@lastfun .package unpacker abd repacker would be nice anyway. I have only xor tool rest is copy *.*

[lastfun]

ok, in 3-4 days (unpaker)...

 

[Hycker]

ok, in 3-4 days (unpaker)...

okay so what i did
im unpacked config.package with quickbms
then i used command copy /b *.* Config.package
added header and bottom to the new file from the original with hexeditor
copied to gameroot/data
client runs

then...
unpacked original Config.package file
UNXORed loadingtips.configc with key 4D
i deleted chinese words from first data line and added hello kitty beetwen the ""

<String Value="hello kitty" />

REXORed with key 4D
then copy /b *.* Config.package
added header and bottom to the new file from the original one
client crashes with error message

 

[lastfun]

...
client crashes with error message

I think you forget it)

sorry guys ... i have a little free time now ... i rewrote unpacking - test it)
(bad code, i'm sorry, i'm not a programmer)) )
good luck!
