Is there a new unpack file？

[GDL]

So it looks like a couple new files have been shared:

SDEJ_5.53.00_20200806201952_2_5.51.00.vhd
SDEJ_8.40.00_20211202173103_2_8.20.00.vhd

I'm not entirely sure but I think they are unencrypted, I can see the file structure and a bunch of *.farc files inside which means we could get the updates from both files.

[f2dr0]

You can open that 8.40 file?

[GDL]

I havent been able to mount it but I can see all the files using a hex editor

Differential Virtual Hard Disks. Semi-useless without the parent disk. You could probably manually pull out new files but that's it and it seems really hard.

Probably, I was able to extract some files by just finding all the "FARc" headers and copy-pasting that chunk of data to a new file and use the scripts from spirit void in the first page of this thread to extract them, like I said, nothing seems to be encrypted and as far as I know the FARc files don't include the length of the file itself to be able to parse it without mounting the vhd, which I havent been able to do, but all the data is available, this is a list of some of the contents I found in the VHDs:

can you upload the files or teach us how to extract from vhd ?

[ailephi]

Probably, I was able to extract some files by just finding all the "FARc" headers and copy-pasting that chunk of data to a new file and use the scripts from spirit void in the first page of this thread to extract them, like I said, nothing seems to be encrypted and as far as I know the FARc files don't include the length of the file itself to be able to parse it without mounting the vhd, which I havent been able to do, but all the data is available, this is a list of some of the contents I found in the VHDs:

bruh I just did what you said and couldnt believe that a simple copy-pasting on a hex editor actually works
thank you for the tip

Maybe someone can come up with a script to parse all the farc files

[ailephi]

Anyway I found a problem

The quickbms script cant seem to extract the tex.bin from the 8.40 servant farc files
but no problems with the 5.53 weapon farc file

though granted I only did it to one file per version,



here's the sample file
https://drive.google.com/file/d/1tRNfb6 ... sp=sharing

[ailephi]

anyway if im reading this correctly, 8.40 should be the CCC collab update

svt_0060_s07 is drake's skin
while i can only guess svt_0137_s01 as welfare BB and then the two Alteregos

[Spiritovod]

I can't check stuff and will not be able to do it in around two weeks, but if those vhd are differential disks, they contain only patch data - that means for totally new archives dataset will be complete, while for already existing archives there are only partial data, which should be merged within virtual file system first. Obviously, you can't fix existing script or create new one to parse incomplete data, except for implementing manual workarounds for each particular error, which doesn't worth it.

Right, looks like we can use SDEJ_5.53.00_20200806201952_2_5.51.00.vhd to upgrade the files from 5.51 to 5.53 that are already shared in Fate Grand Order Arcade Ver.5.51.7z but the changes seem to be minimal, also, there is no base file v8.20 that can be upgraded with SDEJ_8.40.00_20211202173103_2_8.20.00.vhd from 8.20 to 8.40 , but as far as I can tell this last file was extracted from the SDEJ_8.40.00_20211202173103_2_8.20.00.app which was pointed out in a previous post as nearly impossible to be decrypted without the original hardware . . . well, looks like someone has it and is doing it, I hope we get more

(I wonder if the .app and the .vhd can be used comparatively to figure out the decryption method )
