From the link provided by Xiron:

Code:

Basically these ZIPX chunks are used only for the TXT files and they
are probably obfuscated/encrypted.
Now the script no longer breaks at that point and extracts everything.
There is no solution yet for these TXT files.

Encryption like xor keygen. Key must be 256 bytes. For each file encryption key is different.

Here my tool. Supported files *.TXT, *.XML, *.SF, *.CFG, *.CSV, *.LXFML

Code:

[Usage]

Example decrypt

Code:

[Example]
        LWDecryptor GAMEVERSION.TXT GAMEVERSION_DEC.TXT

Also you can encrypt it back, example:

• Fixed problem with files size more than 30kb

LWDecryptor_0.2.rar

It's RC4 using the size of the file as key.
I'm modifying the script to do the decryption on the fly.

I have updated ttgames.bms but I don't have a sample to test.

Version 0.7.2, let me know if this one works (no errors and decrypted txt files).

Deadbot, posted Tue Sep 29, 2015 8:36 pm (7839)

empty text files with 0kb

Could you please refresh and redownload the script?
There was a bug that I fixed 2 minutes after the initial upload, you should see "math TMP2 = SIZE" at line 312

its worked but some text file still encrypted/obfuscated
all another files has been decrypted...

Ekey, do you think this problem is related to the 30k thing you said?
Any idea?

Ekey, posted Tue Sep 29, 2015 9:35 pm (7850)

You need decrypt file data by blocks with maximum size 0x8000

aluigi, posted Tue Sep 29, 2015 10:09 pm (7855)

---

so I guess that the encryption is performed after the decompression (CHUNK_SIZE).
I feel blind because I don't have a ZIPX sample to test, would be cool to have just the part from the first big (>0x8000) ZIPX to the next one.

Script 0.7.3, I guess I have solved the problem.
Basically in the first version I modified CHUNK_ZSIZE that was later used to reach the next offset, that one was the bug.

In the RRU post I linked in my first reply, it also states that the game can no longer run with extracted files.
