Extract the audio files from songname.fsb.xen files ?

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:

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.

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)
