[dongdong]

Hi,guys,I've played game of iris online.
I want to extract the game resource files, but the following error(use zip.bms):
Error:unknown ZIP signature 10585 at offset 0

Please help me, thanks.

bin file:http://www.sendspace.com/file/nkafcu
sample file:http://www.sendspace.com/file/rh85cu

game:http://iris.enpang.com/event/2010/0401/

zip.bms must be used only with zip or zip-like files.
dymok is obfuscated in some way and it's used by mkonline.exe

you are really lucky because I had an intuition and it revelead to be the correct one:

Code: Select all

# Iris Online
# script for QuickBMS http://aluigi.org/papers.htm#quickbms

get SIZE asize
get NAME basename
string NAME += ".zip"
filexor 0x69
log MEMORY_FILE 0 SIZE
filexor ""
for i = 0 < SIZE
    getvarchr TMP MEMORY_FILE i
    math TMP2 = TMP
    math TMP  >>= 4
    math TMP2 <<= 4
    math TMP |= TMP2
    putvarchr MEMORY_FILE i TMP
next i
log NAME 0 SIZE MEMORY_FILE

print "the zip password is jZKCZ/aDV/ORScsYCEAK=n4BH"

note that I would have never download the whole game client so bumping and PMing was totally useless, I repeat: you were lucky this time
