Is NBA 2K15 unmoddable?

[TBM]

I'm getting help on another game modding website. This is what I have so far:

"I am working on the archives for 2 days now, i am planning to write an explorer for this. The archives contain tons of normal zip files using LZMA compression as well as some gzip files using lzma compression."

Yes i'm glad i helped you in xentax

[TBM]

Oh shit, haha. Yeah, thanks for all the work you're doing.

Hi
I am working on the archives for 2 days now, i am planning to write an explorer for this. The archives contain tons of normal zip files using LZMA compression as well as some gzip files using lzma compression.

I know how to extract both of them, but the dds files i got are really really unpleasant.

I was hoping that i could find my way easily on the files and get to the 3d files which i am really really interested to reverse, but then these textures came up

ALL files have their proper dds headers but they cannot show properly nowhere. At least in the tons of different software that i used (including a custom made opengl texture viewer)
I guess it will need many more than that to first properly decode the textures and then get them back ingame

Here is our hope

I'm looking to find what was gamedata.iff did you saw something like that?

even if i had extracted something, i couldn't even tell whats gamedata.iff

I'm working on the archives right now, i think i am getting somewhere with the archive structure. But i'll need some time to get it working.
My intention is to write an archive explorer at first. After that it will be other guys job to identify the files

And to spice it up, i've discovered zlib compressed files as well

If i could describe the archives in one word, this would be WTF IS GOING ON HERE?
Every new offset is just another surprise

thanks for your work so in a perfect world:

1. We use you tool to extract data
2. We eventually mod some files
3. We pack data again with modded files

Correct?

Correct?

I have no idea how the packing back will work. I don't see any folder like structure so there is no possibility that the game will load something out of the archives.
Now packing back into the archives seems easy, but its very very limited and dependent on the size of the modded file. I guess that altering textures will work fine for now so this is the first packing attempt i'll try to make.
But on the steps you have mentioned the current status is 0.1

There is a program called offzip that searches inside binary files for zlib compressed data. I was able to extract thousands of zip files from some of the container files. It doesn't mean much, but it's a start. Like gregkwaste said, getting stuff back into those container files are going to be a pain unless we can find some kind of update folder and put modded files there. Finding the correct filenames will be a pain as well.

For the zlib files there could be some real file names. For example in the 0W archive that i am working right now i've located a zlibbed file called dorna011.cdf. As for the zip files, they ALL contain the file names, what's not in there are the directory folders and stuff :S

This is huge also as soon as they'll release updates of the game we'll have even more informations...

[Kevin]

Let's wait for the update of the rosters so that we'll see how the files actually work and we are ready to go.

[TBM]

Oh shit, cdf files still. There's hope.

[Kccitystar]

So what I'm seeing is that the files that used to be out in the open that we could mod (like dorna011.iff) are now in archives with some insane compression/encryption method?

It seems so....

I suppose they just changed compression method but it would be very difficult to think they've changed EVERYTHING.
So gamedata, dorna, uniforms should be packed inside those big files......

Good news could be: they can't update a court and release a 350mb file....so a patch folder with files override could be the way to release official patch from 2K for courts/shoes.....


Look at the net texture and physics for example....same as old gen

[jmmontoro]

There's like 6 GB of mostly empty bytes in C:\Program Files (x86)\Steam\userdata\[username]\282350\local I think this is how they update stuff, they fill those empty bytes.

I hope 2K, which have an obvious interest in letting their game moddable, left us some hints.

Anyone of you know a modding team currently working on nba 2k15 ?

I think it's too early at this point... it's a new engine, those are not the same iff files as we got year after year with current gen.

[Donatinini]

Right, in fact I just mingled modders with hackers.

So, any hacker team on it ?

Yeah, that's true, but not insane compression at all.
I've managed to correctly extract all 300k+ files out of those archives. But inner file formats are also somewhat different from what we saw in previous years. So, Working forward...

Roster files are encrypted with an insane method.. unfortunately. Still possible to edit them in-mem, but i've never touched them that much this year.

[TBM]

Do the iff files open in 2K14 RED MC? I'm guessing not, but figured I'd ask.

[Sman21]

Why would 2k want to help modders?

All 2k see mods as is lost money.

Any free mod that slightly improves the game or adds to the game.
Is seen as something they could of possibly added as DLC.

The ex modders now working at 2ks first job was to probably explain how everyone mods and help find ideas on how to stop it.

Are we really gonna start in with this bullshit again?

[Andrew]

The notion that folks like Leftos and JaoSming were hired to stop modding is a paranoid conspiracy. We really don't need to go down that road, as it's disrespectful towards a couple of people who have done a lot for this community, and will do great things for the game.

The suggestion that 2K isn't necessarily going to be forthcoming with information about making the game moddable, in part because of licensing agreements and whatnot...well, that is fairly likely, and while it's unfortunate for us, it's an understandable position.

[Sman21]

Hmm obviously a touchy subject.

Sorry havent been around for a while.

Didnt say they were only hired to stop modding.
They were hired due to the skills they showed with their modding abilities.
Ofcourse they werent hired to stop mods.
They would of however sat down and spoke about the modding scene and perhaps give input on how to make things harder.
That is not why they were hired though, thats just smart business to find out what the new staff know

look at Jaos blacktop mods for eg
2k see that and dont think great mod.
They see that as great addon DLC content.

Thats why they were approached.
Helping to make things harder for modders is a just a bonus of hiring them.
Not why they were hired.
