I'm trying to extract the audio files from some songname_1.fsb.xen files from the xbox360 Guitar Hero. Using fsbext I get a message saying file probably encrypted enter password. How do I decrypt the files ?

Any help would be much appreciated.

that .xen extension make me thinking that the file you have is still encrypted for xbox360 so you must decrypt it first (I don't know the x360 world so I don't know what tool/stuff is necessary).

instead the encryption referred by fsbext is the fmod encryption which is easy to identify because the password is partially visible from the tool.

I read somewhere when Googling around for info that the .xen has just been tagged on. So I removed the .xen to make the file just a .fsb. I used fsbext on the file and it's still asking for a password. I'm guessing that this is the fmod encryption you mentioned. You said it is easy to identify the password. How do I work out what the password is ?

Sorry for the noob questions, but I've never worked with fsb files before.

Your help is much appreciated.

Thanks.

if the file is encrypted with the fmod encryption you should see parts of the password after you type a question mark '?' when fsbext asks to insert the password and shows two hex dumps.
if you want I can take a look at the file, I need the first 100 kilobytes to verify it

Thanks aluigi, that would be great if you could take a look at the file. If anyone can extract the tracks it's you ;o)

I've uploaded it here:

The download link is: http://sharebee.com/78342679
Filename: File4test.rar Size: 18.91 MB

I really hope there's a solution to this.

Thanks again.

It's a 31 byte key with nonprintable characters, I got it from the 0xFFs at the end, here's a little utility to decrypt: http://hcs64.com/files/gh360_xor00.zip

might as well use luigi's own program for it, didn't think of pasting the bytes in like that

it has been difficult because it's the first time I see a non-plain-text password used in fmod but... I did it :)
the password in hexadecimal (so not the one you must use) is:
Code:
43 2a 36 32 d8 be c0 ac bb 5d 72 e4 73 7d 5a 79 78 ee 1e 61 36 9b 26 04 a1 82 9c ae 5c f3 d5


how to insert it in fsbext?
simple, take the attached file and then:
fsbext -d c:\output_folder File4test.fsb < pwd.txt

I did it by hand but I have verified each byte, so should be 100% correct

Awesome work aluigi and hcs ! I knew you could do it :o)

I'll try it out and let you know how I get on.

Many thanks guys, really appreciate it ;o)

Both methods worked great ! Thanks again. I've just got to work out how to convert the multichannel xma file produced to something useful.

ghwt_tools_1.2.

Tools to decrypt fsb4 files (i took a look at hcs' code, and his code looks more robust) (works buggy with gh5, but most songs work I believe). Also deinterleaves xma and mp3 files. I'm working on rebuilding xma headers... but this is a work in progress.

Hi bnw33,

I noticed in your tools 1.3 there's a xmaextract. Will that extract the multi channel xma file I have now to wav files ?
Also ,what do I need to run your tools ? No exe files. Sorry for being a noob :o)

I am looking for the file "fsbderypt.exe". I had it at one point but can no longer find it on my hard drives. Does anyone have it. I am trying to decrypt the songname.fsb.xen files found in GH3 for both PC and xbox 360.

the presence of the xen extension makes me thinking that the file is still encrypted with the xbox encryption (correct me if I'm wrong, I don't have experience with the x360 stuff).

anyway if the fsb file is encrypted with the fmod encryption it's enough to use the same fsbext tool for trying to guess the password (with your eyes) and then decrypting it automatically:
http://aluigi.org/papers.htm#fsbext

otherwise try to use first guessfsb of hcs to see if it's able to guess the password automatically:
http://www.hcs64.com/vgm_ripping.html

alternatively you can upload the first 256kb or megabyte of the fsb file and I can try to guess the password

Sorry for bumping this thread but since the new GH is released, the song data is all kept in a songname.pak.xen instead of several files
None of the previous decrypting tools work, (they say they can't find the key) so these must be different. Anyone know anything about it? Would providing some hex sample help?

no problem, upload the whole file or the first 5 megabytes if it's too big on sendspace.com
they usually change the password of the fsb files

What I find strange is that the file for each song is only 1.2 - 7.5mb depending on the song. They are all found in directory /COMPRESSED/SONGS leading me to believe that it's MEGAcompressed.
Here is a link to one complete song.pak.xen: http://www.sendspace.com/file/76ttqu

this is not a fsb file, so it's totally unrelated to the topic and in any case it doesn't seem a known format

It's a pak file, like i mentioned above which I assume has the fsb files within it. I can't open the pak file because of the xen encryption and thought that it would be related to taking the xen encryption off of an fsb file.

Okay, I'm sorry for the confusion Luigi, what I posted was the pak file which contains animations for that song, etc.
I used XENFinal on an actual song.fsb.xen and it did not work.

yeah it's still xen encrypted because with fsbext there is no result (no existence of fsb password), so personally I can do nothing

Thanks for trying Luigi, it's much appreciated.
I have tried a different xen decrypting script (FSBDecrypt) and it said it successfully decrypted and has created a new fsb file. Now when trying to use fsbext it still says it needs a password...

no password visible so it's still encrypted or there is something missed (for example you dumped the part of another file and so on)

I'm trying to extract a certain fsb file. I've removed the .xen, found out the encryption key, and then tried to extract it. However, when I entered the key into fsbext, a list of files (related to what I'm doing, of course) scrolled by, then quickly exited. How do I actually get any of these files? I'm probably just stuipid, but I'm having problems with this.

In the case that its of any help, I've attached what it looks like right before it closes ( with the file names hidden)

if you have not chosen an output folder with the -d option the files have been extracted in the current one and judging your comment I guess you launched a simple bat instead of using the console so the file should be in your personal folder I guess.

if you are in doubt create another bat file containing the following lines and launch it so that it will display the current folder where are located the extracted files, alternatively do a simple search in your computer:
Code:
cd
pause
due to the success of fsbext now I'm writing a quick update of the tool that will implement a simple GUI (like QuickBMS) so that it will be a joke to use for anyone

I tried the files posted on xentax but they don't have repeated patterns in them so in my opinion they are not encrypted with the classical FSB encryption otherwise it should be visible
