Having trouble extracting anything from the Asset folder (XXX files).

Commands I run: umodel -gui CHAR_SubZero_B.xxx

Error message:
appMalloc:size=808536909 <- FArray::Empty:808536909 x 1 <- FString<< <- SerializePackageFileSummary3 <- FPackageFileSummary<<:Ver=677/157 <- UnPackage::UnPackage:CHAR_SubZero_B.xxx, ver=677/157, game=8000 <- UnPackage::LoadPackage:CHAR_SubZero_B.xxx <- Main:umodel_version=343

or alternatively I run: umodel -noanim -nomesh -export CHAR_SubZero_B.xxx

ERROR: Trying to allocate 808536909 bytes
appMalloc:size=808536909 <- FArray::Empty:808536909 x 1 <- FString<< <- SerializePackageFileSummary3 <- FPackageFileSummary<<:Ver=677/157 <- UnPackage::UnPackage:CHAR_SubZero_B.xxx, ver=677/157, game=8000 <- UnPackage::LoadPackage:CHAR_SubZero_B.xxx <- Main:umodel_version=343

Does this mean NRS is using a new way of containing the game files that makes umodel incompatible, or am I simply going about this the wrong way?  Huh?

Sigh ... Run UModel without arguments. Select game directory. Disable animation. Select "Mortal Kombat" in game list, run.

Is this what you mean? Sorry, still a bit of a newb at this.

Loaded Umod. Selected game directory. Unchecked Animation. Hit OK.


Went into Game Directory. Located desired container file. Then hit Export.


This came up:

appMalloc:size=808536909 <- FArray::Empty:808536909 x 1 <- FString<< <- SerializePackageFileSummary3 <- FPackageFileSummary<<:Ver=677/157 <- UnPackage::UnPackage:Asset/CHAR_SubZero_B.xxx, ver=677/157, game=8000 <- UnPackage::LoadPackage:Asset/CHAR_SubZero_B.xxx <- Main:umodel_version=343

Am I still doing this wrong? I never had this trouble with Mortal Kombat 9, Mass Effect or Injustice.

You fooled me with 1st message. I didn't notice that MK X is a new game which was just released. So, I'm moving thread to "Other games" board.
By the way, try selecting any of "Mortal Kombat" game series in "Override game detection". There's a little chance that old code will work with new game.

Gave it a shot. Didn't work.  Undecided

I assume this one needs to be cracked a different way. Would it be helpful to you if I sent some of the game files?

Sure, send me a few packages and the game executable. I'll take a look in a few days.

Thanks. Is there 32-bit executable file?

Those are the only executable files in that directory, unfortuantely.  Undecided

That's bad. 64-bit executables are much harder to analyze than 32-bit.

Hi Gildor, I wanted to extract from some characters of this game, but with extract.exe, not umodel. I made it with MK9 and worked well, so the question is: do you use a similar process with extract.exe?
I'm getting a similar error message like the posted here (umodel).
Must I wait to you support the game with Umodel and then you will add support in the other apps?
Seems like this game requires a 64bit OS to run.

Hi,
Yes, you must wait. UModel and extract.exe uses the same code base, but just performs different actions on package files.
And yes - this game has only 64-bit executable file, that's why the game is not yet supported, I think - reversing of 64-bit executables is a few times harder for me than work with 32-bit ones.

You use IDA pro? Version 6.6 and HexRays x64 alredy on torrents.  Smiley

Got it. Quickly checked the code - the engine was changed a lot. Previous MK versions used very old UE3 version, and it looks like the company's programmers extended that old version with newer features, but they didn't bother to make it even a bit compatible with original engine.

In my opinion, it's quite possible that the game will not be supported at all - or I'll need to write another one UModel, with support with just-this-one-game. Of course I'll try to support it - a bit later, when I'll have more free time (because this is definitely not a quick task). Even supporting the package format (without extraction of textures/meshes/etc) is very hard, and I'm expecting even more troubles with meshes.
