I'll get that windows binary asap... Hoss: Just comment out my definition of uint32_t since cygwin already has it defined. I'll write a repacker, but it's a bit more complex than unpacking.. I've only RE'd enough of the file format to unpack files: there's still a lot of unknown dwords that have a meaning, just I don't know what. My solution will be to save all that extraneous data and then reuse it when repacking. So you won't be able to add new files to a BF file or create a raw BF file of your own, but you will be able to repack modified data files back into a BF file (which is more important anyways) edit: http://th0mas.sixbit.org/bfunpack.exe - untested windows binary. Make sure the directory you're dumping to exists. |

yes i noticed that, same as when i tried to extract wav's from a xzp file.
I think it has something to do with the compression format the xbox must use? anyone know what codec's are required?

I believe they use a different format type that might correspond to being 5.1. WAVE files are not compressed (unless microsoft is packing compressed audio data into a WAVE format file and pretending it's a WAVE, but that'd be pretty dumb)

i also find it puzzling that most files are 2 kb, with the exception of a few.

Me too.. but that is seriously what the file says is there!
I'll look into it again, maybe that BF file is substantially different, but as far as I can tell that is what's going on.

Yeah, most of them are all WAVE files in Sound_Cmmon.bf, at least to some extent..
As an update: I'm working on the understanding the directory structure, following which I'll have a new unpacker and also a repacker.
update: I'm reading the directory structure.. I could dump it all pretty easily, but ~90% of directories in the list are empty. It seems that the creators of the game left the structure for the full version intact, and only deleted the files from the BF.

Just been trying the extractor programs.
I have been looking at the .bin files. They look like they may be either compressed or encrypted?
There are some common headers in the bin files. They all seem to start off with FC XX XX XX 00 D0 07
XX could relate to a start or end or length address, the 00 D0 07 seems constant on the files I have looked at so far.
ff01eabc.bin
00000000h: FC E7 CA 01 00 D0 07 00 89 FB 00 00 0D 48 00 00 ; üçÊ..Ð..‰û...H..

player98198: Nice program (although I haven't tested it, I don't run windows..) I have two questions for you about the file format: the offsets to the filelist, at 0x44 that consists of two dwords (offset, unknown).. what is that second dword in each entry? Do you interpret it? I currently just store it and reuse the same value when repacking. same for the dwords in the file info structure and the directory info structure's.. there's 4 or 5 dwords, I know how they reference parent directories (and hence can build the whole directory structure) but what are the other dwords? If someone verifies that player98198's program does repack successfully please tell me so I don't continue writing my own, I have better things to do  . However if it doesn't work I'll finish my repacker. |

i have tested Player98198'packer, it has some little problem sometime but seem to work ok.
A feature is missing, i'm working on using .bf from Original, but on original there is two .bf, on for textures and one for maps.
With this tool i can extract and repack both individually, but can't merge to obtain the same file as for DEMO...
if you Thomas or Player98198 can add this possibility it would be amazing....

if you wish to repack files of your own then what you could do for now is
1. create a dir list of the folder that contains all files u want to add
2. put all your files into the @Extracted folder
3. replace the names in the -LBA.txt file with your names you made when u did the dir list (use excel or that type of app)
now one problem that exists is that there is a filecounter that i implamented. so that would be a big problem because tool will not know when to stop because it refers to the original munge file. i will try to figure out a better solution when i have some time.

not sure what that other one could be, my tool leaves it as-is when reindexing.
btw,there seems to be no folders but if u open up the lba.txt file and replace the "_" with "\" then my tool
will create folders. it seems to be a little bit more organized that way.
