[NBA2K15 PC] New File Format [ Solved DDS and PNG images ] !

[Andrew]

Lets start
Files are stored in big files as a subfile/subzips
Example: 0B has 4664 subfiles


So the 0B file structrue..
1st subzip/file starts at 00000000
2nd starts at 00466AA4
3rd starts at 007167A5

Subfile HEADER is 94EF3BFF [HEX] and at offset START + 8 we have the info where next file starts
EXAMPLE:
1. At 00000008 we have 00466AA4 and that is start of 2nd file [ so 1st file is from start to 466AA4]
2. Than go to 00466AA4 offset 00466AAC [ 466AA4+8=466AAC] we have 002AFD01
3. To get start of 3rd file go to start of 2nd file and jump to 2AFD01 from that place 466AA4+2AFD01=007167A5 and that is start of 3rd file

Clear bro,
Subfiles once splitted are just zlib compressed?

[nesa24]

Clear bro,
Subfiles once splitted are just zlib compressed?

yes they have ZLIB

[maumau78]

Clear bro,
Subfiles once splitted are just zlib compressed?

yes they have ZLIB

Clear so final question is how do i get files Names for every archive?

I mean i can write a vb.net program that split every big one....then using vb.net zlib library I just read the header to find chunk split name?

[nesa24]

i dont think that all are zlibed but some are
in subsection there are subsection like subfolders in subfolder
example 2nd subsection of 0B have 5-6 subsections in it [dds files face_wrinklecolor_o_B2122AB31469EA20.dds ,face_normal_o_53C423D1AEC5B3D5.dds ..]

Its way more complicated than this, i am working on 0W, i can confirm those sections you described but its way more difficult to parse them.
In some of those archives like the one you mentioned there are offsets defined for the compressed files. In some others there are offsets that do work only with the decompressed data so you can't use them to parse the compressed data, you need to read additional sections for this. This is what happens with the iff files for example ("0x305098F0"). I've found sections in 0W that start with 0x94EF3BFF just like the others, there are multiple parts defined but there is only one compressed chunk.

Just a question, how did you get all those offsets? Are you using offzip or some self scripted thing?

using a custom build file research tool... and memory tracing

EDIT
As of 0W file starts are

how come that this topic goes to help and requests?
like las year i think it should go to releases and previewes

I agree 100% with Bro Nesa24....

Nesa24 is doing a lot of work should be placed in releases.....

[Kevin]

TBH, I'd like this to go in the Tutorials section rather than the releases. He hasn't released anything and I think this is more of a tutorial than a mod.

Are you Joking?

Nesa24 work is top notch and requires a lot of work and time......it's hacking 2k15 file system!
We all be more grateful for his big work....
How this could not be in Release section?

[Kevin]

I don't know what to say.

[Angelo]

This will be transferred if he released something as of now all i see is some info on the file structure of the game..

[Andrew]

I don't know what to say.

Me neither. I can't believe this is even an issue. I honestly can't.

It isn't a release, or a preview. It's not a tutorial, at least at this juncture. It's a development thread. And seeing as how the Help & Requests section is also for helping modders - it was originally Patching Help & Requests, but people insisted on ignoring that and posting technical support questions, so we ultimately decided to include those here as well - I don't see how it's inappropriate, or disrespecting anyone's work.

Glancing back at the Releases & Previews section for NBA 2K14, I can't see any stickied threads like this one. Honestly guys, I'm flabbergasted that we're even having this conversation. It's not like the Releases & Previews section carries some kind of prestige that Help & Requests doesn't. Given the traditional purpose of using this section to ask for help with modding, it seemed like a logical place for a workshop thread, that I presume would eventually be spun off into different tutorials and resources once things start to get figured out.

I don't know what else to say. I'm absolutely floored by the fact that this is somehow a big deal, or that it's at all disrespectful. Wow.

[R4zoR]

Yea I completely agree with Andrew, if you guys actually wanted to create these tools so badly, you could just cooperate and get this thing done sooner and not make it such a big deal about where the topics are, yea i know it's a hard work to create a random tool, everything is hard in life, even nose picking. So let's do this boys(not the nose picking, the tool part)

nah m8 how dare u. who do u think u r m8.



Yeah, there's nothing wrong with keeping it in this section.

Not saying anything about disrespect
Only asked why.. And i wrote why i asked [ AUDIO Research was moved to Release section and i didnt make any tool at that time ]..
Tool will come once subfiles are done
No nosepicking its just small amount of time to edit
I am sharing info for reason that is same as of 2K Audio Format for past years and that is to get tool ASAP i realy dont care if someone alse make it
This is community and we should share what we know/find

No need to get into this deeper i asked and got response..

More info about format when i find time for editing

[TBM]

Speaking of audio, someone mentioned, maybe it was you, that the audio was .ogg this year. Is that OGG vorbis, or something more like Wwise, which is a common game ogg format?

[Andrew]

Fair enough. I was just surprised that it even came up in the first place. Carry on.

I wrote that it is OGG
More info when i get into it

[nesa24]

i have made some progress in research and will upload tool as soon as its ready
no specific date but tool will have
*export of subfiles from archive [ one or all ]
*import from directory to archive [ one or multi ]

[Kevin]

Holy crap, that's amazing!

Awesome, good job man, so everything exports correctly now, talking about texture wise?

[agolden]

incredible, also great pic you put in your tool haha
