Hi,

Operation Flashpoint 2 by Codemasters is out, and the game uses the EGO Engine. The variation of the EGO engine used in Codemasters is the variation used in GRID x360.

Each .000 is 8 megabytes large exactly.

My goal is to obtain the music from the game.

Can anyone help me?

Here are the first 10 of the 375 files: http://www.megaupload.com/?d=S6011IRE

Thanks very much in advance!!

eh eh eh don't worry I follow xentax too so I already saw your post :)
if there will be updates I will post them on that thread

in the meantime I can say that it uses the LZSS algorithm but these files are only raw data so you should have an index file somewhere.
no index, no party

Thanks! An index file? There's a .nfs file at the end. Looks like it might be an info file. I'll upload it for you once I get home.

Edit: Here it is: http://www.megaupload.com/?d=JDF8KWW2

Damn, that doesn't look like the index file. If that's not it then I don't know where it could be. However, I used this tool: http://forum.xentax.com/download/file.rar?id=898

And it seems to work; it decompresses from 8 mb to 27. However, I don't even know if it decompressed correctly. No noticeable header strings. I see the text from the beginning of .000 though, if that helps.

There's been progress on Xentax and you've posted a QuickBMS update on decompression. However I'm still rather confused as to what I need to do to get the audio files/decompress it. Sorry if I sound impatient, I'm really pumped for this music. ;)

I have wasted some time on the format but it's too boring because some references and fields are "strange" and so it's all chaotic... blah

Darn, okay.

only to update this thread (in case someone else is reading/following it):

Hi Alugi, Maddog from Xentax here :)
I would like to continue OF 2 discussion here if you don't mind.
I see here
"I have wasted some time on the format but it's too boring because some references and fields are "strange" and so it's all chaotic... blah"
As I mentioned at Xentax that there is a mission editor that extracts some game data but I was wrong it doesn't in fact. It uses it's own files that they provided during game installation. My bad here.
You updated your QuickBMS and the script that we were using at Xentax failed now with less than 174kb extracted data with following message

I know you deleted script because it wasn't working completely, but it happened to extract almost full game with 0.32 Qbms version and >2gb switch. Most files are usable but some are corrupted.
Now 0.3.4b fails after dozen offsets. 4 folders only and 43 files.
We can extract fine file list with offsets and file sizes.
File.txt
It count's around 31k files. Address range are from 00000000 to 048db8dc.
I experimented with extracting different string name here:

for example:

Interesting is that it extracts files in folder AMBX fine, but after that it start extracting files other then in that folder and name those folder names, like they are file names and hangs with same error mentioned above.
Every extraction with interchangeable string "foldernames" now fails at 174 kb and 43 files in 4 folders.

Best regards.

No
win_000 to win_520 is 8 mb and win_521 is 1 mb. so in total 521 files with win.nfs 522.
win.nfs is 2.75 mb.

Well, you got the point. :P

this thread can be also closed because as written on Xentax mine was only an experiment and being the "merged" file bigger than 4gb (0xffffffff) it can't be handled by quickbms.

P.S.: the fact that the extraction fails soon with the newer versions of quickbms is correct because the files extracted previously were WRONG (now I no longer remember the names of some of these wrong files where the content was messed after some bytes).

Thanks on your quick response, anyway game is already trashed by codemasters so it's not worth time or effort.
