StarWars Battlefront Closed Beta

[CZW]

hello

i'm looking to unpack .cas files

engine : FrostBite3



test with DAImoddingTool, we can open it, but cannot extract or see anything ...

So the packages seem to be the same as DAI and BF4/H and textures are full DX11 dds files and here are some of them.

Credit goes to danielmm8888 and PistonMiner for creating the tool though.

Models are next on their list and than sound and the 5 odd videos that are in the game files.

So am I right to say at the moment the battlefront files cannot be extracted I'm trying to extract the sounds.

If not I hope someone can look into adjusting the script to extract the files.

[daemon1]

Checked danielmm8888's script. It just dumps all files from CAS with no names, including sounds. I can make XAS extractor, if they still didn't make it.

[daemon1]

Well, it seems my decoder already supports it, because it's standard XAS audio files.

The only thing you need now is to split chunks into individual files. This must be easy.

OK so this is what you can do now:

1. extract all chunks from cas with danielmm8888's script

2. run my tool Frostbyte_chunk on each chunk to merge uncompressed chunks into raw data

3. if chunk has multiple audio files, split them somehow

4. decode XAS into WAV with my tool xas_decode

Checked it with some battlefront music and steps sounds, all worked ok.

[durandal217]

OK here's my question though. Where do I get danielmm8888's script because I checked everywhere and can't seem to find it.

[daemon1]

This is what i googled:

https://raw.githubusercontent.com/Pisto ... tractor.py

But maybe JakeGreen knows better, he was talking about some tool. I don't know who they are or how to contact them.

Thank you so much, this is different from Frank's script and I'm having a little bit of trouble with it could I trouble you for some help? I've been messing with the script but I can't seem to get it to work. I initially thought it was "OK this is a piece of cake just input the directories and hit F5"

so I'm putting.

Code: Select all

# Get a handle to the CAT file and get its size
catFileName = sys.argv[1]
catFile = open(catFileName, 'C:\Battlefront\Data\cas.cat') 
catFileSize = os.path.getsize(catFileName)

# Skip the signature
catFile.seek(0x10)

# Create the folder where we'll be dumping the content into (if necessary)
if not os.path.exists("C:/dump/"):
    os.makedirs("dump/")

every time I do I get this.

Code: Select all

Traceback (most recent call last):
  File "C:\Battlefront\Data\CASExtractor.py", line 8, in <module>
    catFileName = sys.argv[1]
IndexError: list index out of range

What am I doing wrong?

[daemon1]

This script is supposed to be run with command line arguments. If you want to run it without them, do this:

Code: Select all

catFileName = "C:\Battlefront\Data\cas.cat" 

only change 1st line, not others

p.s. also note, I'm not aware if any scripts exist to split audio chunks. The one for DAI doesn't work, maybe there are others. I was splitting them manually. If none exist, I can write a new splitter.

[durandal217]

EDIT: n/m i got it I had to put the script in the data folder.

alright extracting the files now!

It worked I got 4,267 files they extract now I just need to work on batch extracting and converting. I haven't seen any example of splitting audio chunks yet but could you work on a tool in case? And if there are multiple files exist what hex code or tag would I be looking for in the file?

I hope all of the gunfire and vehicles sounds are here, that's what i'm after the most.

[daemon1]

And if there are multiple files exist what hex code or tag would I be looking for in the file?

No, chunks are just audio files merged together, there's no way to know how many files they contain. This information is in corresponding EBX files, and we don't have their names now.

We've already gotten model texture and sound extraction to work.

Daniel, have you released the tool? or is it still in a work in progress? is there a way I can get my hands on it?

[daemon1]

Probably no, or it's a secret tool, he's not answering PM's either. So we don't know if their tool work correctly with sounds. Had you any success finding the sounds you wanted?
