Blur .pak files

[btlncn]

I have some .pak files from the game Blur. If someone could help me decompress them I would appreciate it. I've included files from both the 360 and PC versions of the game.

unfortunately the table with the name of the files is obfuscated in some way, for the rest the following is the script for QuickBMS compatible with both the PC and the 360 version:

*edit* the script has been updated!

Thanks a million.

Well it does work for the ones I sent you but on the others its throwing an error. (Something about an incorrect zlib/deflate input as well as a negative output size for the PC version, and trying the other xbox files cause a hard lock up). Most of the others ones are too large to upload but here is one that didnt work that is a reasonable size. I uploaded it here.

ok I have updated the script, anyway I can't assure it will work with the other files because the format is strange and I used work-arounds

[aluigi]

I have found the xor key for the names so now the new script I have linked in my original post extracts the file with all their names :)

Next time use Sendspace or Mediafire.
The site you used is so damn annoying as hell!
Full of advertisements and scripts wich makes downloaling impossible.
And even impossible the downloadlink after finished counting.

I have just updated the script (0.2.1) adding another work-around for supporting the non-compressed files.
I hope that now it will work with the majority of the archives.

Thanks a lot for this!

If anyone is interested, here's a *.baf extractor I wrote. All those baf archives are contained in the pak files of Blur. Only tested with the 360 version though but I guess it works the same with the PC version.
EDIT: updated the script with an XMA header writer! All extracted XMA files can be decoded with toWAV now - correct frequency and channels obtained from baf header.

Code: Select all

Thanks very much, sorry about the megaupload thing, I just used the first one that popped up.

ops sorry my fault, I compared SIZE with the aligned size of ZSIZE and forgot to compare it with the original ZSIZE :)
updated version 0.2.2 (the last? maybe)

Aluigi, the bms works perfect
Alphatwtythree i get errors in the audio files i'm using a PC version:

- open input file env_traffic.baf
- open script bluraud.bms
- set output folder .

offset filesize filename
------------------------------

Error: incomplete input file number 0, can't read 4 bytes.
anyway don't worry, it's possible that the BMS script has been written
to exit in this way if it's reached the end of the archive so check it
or contact its author or verify that all the files have been extracted
