Rapidshare is awful and banned. So I can't download the game. Is this a trial version of some kind by the way?

Concerning the file, it looks like it is Zlib compressed.

Code: Select all

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

idstring "\xcf\x01"
get ZSIZE short
savepos OFFSET
clog MEMORY_FILE OFFSET ZSIZE 0x10000

get DUMMY byte MEMORY_FILE  # zip?
get FILES short MEMORY_FILE
for i = 0 < FILES
    math OFFSET += ZSIZE
    get NAMESZ byte MEMORY_FILE
    getdstring NAME NAMESZ MEMORY_FILE
    get ZSIZE long MEMORY_FILE
    get SIZE long MEMORY_FILE
    clog NAME OFFSET ZSIZE SIZE
next i

This bms can unpack the *.PAK file format of the Orneon Limited games ("Echoes of the Past - Royal House of Stone")
But can not unpack the *.PAK file format of the Orneon Limited games ("Secrets of the Dark Temple of Night")

Didn't work with data.pak (460Mb) in Echoes of the Past 3 - The Citadels of Time CE:



Please help

Every file data is encrypted (with a simple XOR encryption), so first need to decrypt before we can decompess it with zlib.
Here are two passwords I found:
"Echoes of the Past 3- The Citadels of Time CE" -> Xor password = 'e34596'
"Secrets of the Dark - Temple of Night CE" -> Xor password = 'tm7224'

If someone finds another problematic Orneon Limited game, just let me know, and I'll try to find the appropriate password for that.

The modified lines for the QuickBMS script:

Code: Select all

    filexor  "0x65 0x33 0x34 0x35 0x39 0x36" OFFSET   # Echoes of the Past 3 - The Citadels of Time CE
    clog NAME OFFSET ZSIZE SIZE
    filexor ""

Or:

    filexor  "0x74 0x6D 0x37 0x32 0x32 0x34" OFFSET   # Secrets of the Dark - Temple of Night CE
    clog NAME OFFSET ZSIZE SIZE
    filexor ""

Thank you Bacter, I appreciate it.

Here's the password for the QuickBMS script:

    filexor ""
