MK 11 unpack, repack

[ponaromixxx]

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

Could you upload oodle dll from game?

ok updated

normal oodle works fine

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

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

[Shokoniraya]

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?

[Demonslayerx8]

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.

[interloko]

Decompress but i got this:

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

[Shokoniraya]

Decompress but i got this:

maybe compression is different! can you upload error file? (tweakvars.xxx)

Here is the file

[Murdoink]

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

[Shokoniraya]

i need one other small file with error

[Egor705]

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

[masagrator]

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)
