Metal Gear Solid HD Collection(Xbox 360) - .xbarc

[AnonBaiter]

Okay, so the .xbarc file seems to be the same thing as .psarc(similar structure, etc). I don't see archives like this very often in some games but anyway...
Here's a full file of it.

Again I've never seen anything like it on a Xbox 360 game, but I feel that kind of archive type is quite common.

There are more "compressed size" fields than files, it may be related to a mechanism for updating the archive and that would explain the 73% of coverage.

[aluigi]

No, it's related to chunked files so the script will be updated later.

[AnonBaiter]

All right, I'll wait for it.

[aluigi]

Script 0.2

[AnonBaiter]

What a script. Say, do you see any differences between an .psarc file and a .xbarc file?

[aluigi]

If you mean brink.bms they are completely different.

[AnonBaiter]

So you say their structure is different? Okay.

Anyway, these files don't work with the script:
mgs2_xbarc.rar

The first .xbarc file extracts that exact file to infinite quantities despite being empty(about 0KB, no less!) and the second one just triggers an error:

So they should be .wmv files instead.

[aluigi]

wma and wmv have the same magic.

I don't know why but here the script works perfectly with mgs2_1.xbarc_0_2452338969 while you get the crash immediately at the first file.

[AnonBaiter]

Which is why it bugs me that I'm the only one getting this error just now. I'm using the quickbms_4gb_files.exe app if you're curious.

[aluigi]

Are you sure the script you are using is the original 0.2 one?
The crash you have there is inside the xmemdecompress function while trying to read a byte from the input located outside the input buffer.

Here there is no problem with quickbms.exe or quickbms_4gb_files.exe or with the -9 option and so on.

Try the following script on mgs2_1.xbarc and let me know what you get:

Code: Select all

comtype xmemdecompress
clog "test.dat" 0x000458dc 0x0000021c 0x0000091f

That one is the first file on which you get that strange error.

[aluigi]

In the meantime I have fixed the script with version 0.2.1 for working with files that have a size of zero like those in mgs2.xbarc

[AnonBaiter]

It's happening to me again, even with a different file:

Code: Select all

  0000000000000000 4358       0000000000000d07.dat

The file in question:
mgs3_common.rar
Yes, the script is updated with version 0.2.1. Maybe I'm doing something wrong?

[aluigi]

An error in the increase of the offset.
You MUST reuse the script on the other archives you extracted because the size/content of some extracted files is probably wrong.
Script 0.2.2

[AnonBaiter]

Huh. I didn't know there were filenames scattered around the archive. Do you?
(and yes, I edited your script to have the extracted files have these names assigned to the NAME_CRC variable. sorry)

Other than that, thanks for "fixing" the script.

[AnonBaiter]

And thus mgs3.xbarc refused to work again:

Code: Select all

  0000000000000000 0          0000000000000c66.dat

- 3175 files found in 52 seconds
  coverage file 0     9%   68351195   693945522

mgs3_1.xbarc doesn't seem to be affected as much, but then again...

Here is the file in question:
mgs3_xbarc.rar

Oh yeah, and the filenames issue... this file along with the previous attachment, they all came from their respective archive files (mgs2_1.xbarc, mgs3_1.xbarc) while others (mgs2.xbarc and mgs3.xbarc) had their filenames scattered around the files for no good reason... or maybe it's just my edited script?

[aluigi]

Ok, no problem it's just a bug in quickbms (that I have to investigate) and that check was useless so I have removed it, script 0.2.2a.

[AnonBaiter]

Ok, now it works. Thanks.
