Obfuscated. Here snipped code to deobfuscate

Code: Select all

   for (int i = 0; i < dwSize; i++)
   {
      lpBuffer[i] = 16 * lpBuffer[i] | ((uint8_t)~lpBuffer[i] >> 4);
   }

here is my bms script attempt to deobfuscate file

Code: Select all

# script for QuickBMS http://aluigi.altervista.org/quickbms.htm

get SIZE asize
get NAME basename
string NAME + _fixed.dat
filexor "\xF0"
log memory_file1 0x0 SIZE
filexor "" 
log memory_file2 0x0 SIZE
goto 0x0 -1
for i = 1 to SIZE
   get TMP byte -1
   math TMP z 4
   put TMP byte -2
next i
log NAME 0x0 SIZE -2

Script 0.1.1:

The script automatically decompresses the lzs files too.

Thank you, everyone!

Anyone know where the text files?

Hi Makc, thanks! How you get that? I'll try to use this script but it's not works in all the files on folder. Can you explain? If you want, send me one PM.

Regards.

I'm having trouble to extract the .dat files from the game. The script from the demo apparently don't work with the full game.

It's different than viewtopic.php?f=9&t=7800

Basically here the obfuscation seems the same but there is NISPACK magic and the format doesn't have much sense, number of files followed by "FILES * 4 * 2" that don't match any offset or size.

*edit* moved the 2 posts in the original topic.

Hello.
Could anyone help me with unknown nis lzs compression?
There is no info about compressed/uncompressed size in the header.

I've tried unpacking this file with basic lzss algoritm, but no success.

Game: Disgaea.

@Rainx
I have moved your post in another topic for this game.

In the header I see "dat\0", a sort of size field that doesn't match a compressed or uncompressed size because it's shorter and then "UNMO".
Do you have other samples?

[Rainx]

Do you have other samples?

One more sample: https://www80.zippyshare.com/v/t2LgwJi0/file.html
And that's all. Because other files have normal lzs compression (I mean, dat\0, uncompressed size\0, compressed size-4\0).
