Hello, here comes the new Mortal Kombat 11, and again the developers have changed the modification of resources! As I understand it .xxx have Oodle compression! Does anyone have any ideas how to deal with this?

MK11.exe
Config.zip
Localization.zip
xxx.zip
All_dll.zip

normal oodle works fine

here a test script (not sure can works fine in game or not, but test it)

Code:

#Mortal Kombat 11 .xxx decompressor (oodle compression)
#use on raw files
#Script By Shokoniraya


get FILE_NAME filename
string UTX_FILE = FILE_NAME
string UTX_FILE   "_decompressed"
comtype OODLE
findloc UTX_HEADER binary "\xC1\x83\x2A\x9E\x00\x00\x00\x00\x00\x00\x02\x00\x00\x00\x00\x00"
log UTX_FILE 0 UTX_HEADER
for j
comtype OODLE
findloc UTX_HEADER binary "\xC1\x83\x2A\x9E\x00\x00\x00\x00\x00\x00\x02\x00\x00\x00\x00\x00"
goto UTX_HEADER
get HEADER longlong
get PARTION_SIZE longlong
get COMPRESSED_SIZE longlong
get DECOMPRESSED_SIZE longlong

xmath COUNT_FILES "DECOMPRESSED_SIZE / PARTION_SIZE"
xmath TEST_COUNT "COUNT_FILES * PARTION_SIZE"
math DECOMPRESS_SIZE = DECOMPRESSED_SIZE
math DECOMPRESS_SIZE - TEST_COUNT
if DECOMPRESS_SIZE > 0
math COUNT_FILES   1
endif


math TEST_NUM = COUNT_FILES
math TEST_NUM * 16
math UTX_TOTAL = TEST_NUM
math UTX_TOTAL   16
math TEST_NUM   UTX_HEADER
math TEST_NUM   32
math OFFSET = TEST_NUM
math UTX_TOTAL   COMPRESSED_SIZE
for i = 0 < COUNT_FILES
get COMP_SIZE longlong
get DECOMP_SIZE longlong
append
clog UTX_FILE OFFSET COMP_SIZE DECOMP_SIZE
append
math OFFSET   COMP_SIZE
next i
next j

I tried to use the script. It says: "Error:invalid command "if" or arguments -1 at line 25"

i just tested this script on quickbms 9.2.0 right now and i upload original bms


and we need AES or anyother encrypting code for Coalesed files (usually, they just using aes code in coalesed)
but there is a 32-bit code at end of archive but i tested it and maybe its just a fake code (because its not working) or using somewhere else

can anybody try my decompressor on game and tell me works or not?

I tried it on the switch version of the game, it decompressed the files, but still unsure how to extract the model, textures, or the sound files.

To understand whether it works or not, you first need to extract resources and replace them.

are the coalesced files compressed too? or just encrypted? if so, is there a way to get the AES key to open it?

i need one other small file with error

If you are talking about the one that was created after decompressing then here. Otherwise I don't know wich one do you need.

no, i need an other small .xxx sample with error (it's really needed for fix script)

hi, any idea how long until these files will be accessible to crack for things like textures and character models? for anyone in need of them, i can supply both the pc version .xxx files and switch version (before the update) .xxx files. i would love to be able to find the characters in particular, but i haven't even figured that out yet...
edit: also, the decompression tool works for me!! i'm just not sure what to do with them after that

Surface is encrypted. After decrypting we will know if it's compressed too (compressing encrypted file is less efficient than encrypting compressed file).
But looking at differences between PC and Switch I think PC has compressed coalesced too. Switch hasn't (2x bigger).
I'm trying to check if I can find keys in Switch executables, but disassembling it will take time.

i need two file .xxx with error in my script (needed for updating script)

Your script decrypts blocks, and there are not 2 files, but one with the first two blocks

I need two sample file that quickbms gives error in decompresing, because I have to make sure about compreesion flag and update script!

what block?

I've processed all other files after the error and worked them all, so that is the only file that got it.
In the other hand some files does not decompress, maybe because there is nothing to decompress?

again, I need two small file that not decompressing (I should write this until fixing script )
