Well this game was just released for the PC and I was excited to have a look at the filesystem and try for models and textures...boy was I surprised...and disappointed. It's nothing like the first two, and there's no real way for me to figure out just what is what, and how to extract it. Folders upon folders of files without extensions. I was hoping someone could shed some light on this situation for me, so I can get the models of Grievous, Ultron...and maybe Vader and Sidious if he's in it...
Here's one folder with many folders within.

Here we go
http://aluigi.org/bms/disney_infinity.bms

From the notes in the script:

Quote:

# Notes:
# Many files from the ZIP archives (PK\xff\xff -> PK\x03\x04) can't be
# decompressed correctly. This limitation may be fixed later with a new
# verison of the script. All the other files are perfect.
#
# The kb2 files are Bink videos.

Is there any way we can get it to ignore those 'broken' files when doing a mass extraction?

aluigi, posted Sat Oct 31, 2015 11:15 pm (9142)

Unfortunately I found no way.
I guess it's something related to what parts of the archive can be decrypted or not because many dds are partially valid like 9653cf49\assertscreen_0.tbuf.
It looks like it needs more work.

Anyway the other files and archives (like DBNK and bink videos) are all ok so I suspect that it's something specific of these PK archives.

In the meantime I have updated the script for removing the usage of arrays when handling the PK archives for being faster.

Luigi, could you please make a separate BMS script for just decryption/encryption of ZIP files?

Thanks in advance.

aluigi, posted Sun Nov 01, 2015 10:15 am (9156)

That's not possible because it's not an unique normal ZIP archive, it's like a sequence of multiple 1-file only ZIP archives.

Technically:
read 8 bytes: PK ff ff FILES
read 8 * FILES
(reset encryption)
go to each offset and read 0x1e (PK 03 04), name and data.

I did it
Script 0.2

Ah in case you ask, yes the files of 0 bytes are really 0 bytes (method 8, comp_size 2, uncomp_size 0).
You should launch quickbms with the -D option selecting the whole folder for extracting ALL the archives.
Over 12 Gb of compressed archives is really huge.

If someone is interested to know where the AES key comes from:

Code:

    unsigned char   key_original[16] = "\xEA\x94\x1B\xF9\x99\x01\xA5\x63\x51\xBE\xB7\x68\x88\x14\x16\x04",
                    key[16];
    int     i, x = 0;
    for(i = -5; i < 0x6b; i  = 7) {
        key[x  ] = key_original[i & 0xf];
    }

the script is powerful! it works perfectly!! Thanks aluigi!!!
using the Cra0kalo tool I tried several figures and are all broken

well! they are olaf and luke
someone got better results?

I know the reimporting function is experimental, but unfortunately it doesn't work here

Still no way to export compressed chunks and then encrypt them back?

Well if anyone is interested in figuring out the remaining formats...

Here's the other topics relating to them.

Reimporting the files extracted from the PK archives it's not possible.

Any chance for the textures?

Sorry for the double post, but I thought I should bring up the tablet versions archives are different formatting.

Here's a few samples.

Just fixed in script 0.2.1.
The reason was simply the usage of lzma to compress the files instead of deflate, copy&paste from zip.bms did the job

The script works great, however I run into the point where the script stops and doesn't continue because of an error with a few files. I've seen that you said to use the -D command, but whenever i use the cmd with quickbms, quickbms says there is a wrong command-line argument when I write the name of the .bms file. I can't figure out why because everything is correct. Any help would be appreciated, I believe I'm missing some textures because of the error popping up before it finishes extracting.

aluigi, posted Fri Nov 06, 2015 2:25 pm (9366)

What's the exact command-line you are using?
The correct one is: quickbms -D script.bms input_folder output_folder
You can even create a shortcut to quickbms.exe with -D appnded in the Target property.

What are the errors you get with those few files?

TRDaz, posted Fri Nov 06, 2015 4:08 pm (9370)

That is what I am using, mine was:

D:\qbms>quickbms -D "C:\Users\name\Desktop\disney_infinity.bms" "C:\Program Files (x86)\Steam\steamapps\common\Disney Infinity 3.0\assets\*" "C:\Users\name\Desktop\DI output 2"

I'm not entirely sure how to do the appending of -D in the target property.

And the error i get is the following:



I think the file that it is giving an error on isn't needed for models/textures, but it stops the script from continuing which may be causing me to miss files.

aluigi, posted Fri Nov 06, 2015 4:18 pm (9372)

remove the final \* from the input folder and it will work:
quickbms -D "C:\Users\name\Desktop\disney_infinity.bms" "C:\Program Files (x86)\Steam\steamapps\common\Disney Infinity 3.0\assets" "C:\Users\name\Desktop\DI output 2"

That error is interesting because that file is completely encrypted and not only its first 0x200 bytes.
I will check it.

Hey, out of curiosity, is there any chance this file can be used to find the proper textures for the models or something? The problem is none of the textures in the massive archives are named or otherwise designated to specific models...so there must be some way to identify them...

Ok, only the files with DCT extension are not encrypted.
All the others have their first 0x200 bytes encrypted.
It means that the 99.9% of the files we extracted are perfect and only those few language files aren't (quite important to know considering the over 12gb of these archives and the slowness of the extraction).
Script update to 0.2.2

Just for curiosity, why nobody else except TRDaz noticed this problem?

Oh I see, thank you! Thanks for the update too.

@Doctor Loboto, I was wondering the same actually, the textures are rather hard to find as there are thousands of texture files within the extracted files.

Speaking of textures, aluigi, would you mind having a look at the ones I posted in the respective topic? The PC versions are different from the tablet version, but from the looks of things and judging by past games, the PC versions would be higher resolution.

https://www.dropbox.com/s/501p7vaccho2q1m/Textures.zip?dl=0

The tablet versions are just renamed '.PVR' files, a semi-common mobile format.
