Greetings,can anyone take a look at these files?

Samples here:

Try the following:
download the zip2.bms script http://aluigi.org/bms/zip2.bms
open it with a text editor and replace the 3 occurrencies of the "idstring" command with a simple: get DUMMY long
Now use the edited script on the these dat archives.

Thanks for the help luigi.I tried your script and changed "idstring" to "get DUMMY long"
but i got this error while trying to extract some dat files,can you fix it?

Thanks in advance!
P.S I can upload all game .Dat's if this can help

I meant the whole idstring line
Instead of idstring "PK..." you must have just get DUMMY long

Did i do something wrong?

Thanks a lot! now everything works nice
Edit: Oh..looks like it doesn't work good with some .dat files

But anyways here a more Dat samples,i hope they will help you:

Because not all the files are ZIP archives ("RN" 0x07 0x09 and "QM" 0x06 0x08).
For example:
- file000000.dat is just a sequence of random bytes (maybe encrypted)
- file000079.dat is a PNG image with the first 4 bytes modified (0x8a "RQK"), set them to 0x89 "PNG" to view these files
- file000092.dat is a model I guess with the usual first 4 bytes modified ("GYV" 0x0f)

That's all, there are no other formats.

Anyone have any luck with the .bdae files in this. It's my most requested game to set up and rig 3d models from, I'd appreciate it mucho. The character .bdae can be opened as zip files as well, containing an endian .bdae and a script inside. Past that I'm stuck. My nearest understanding is this game was built right on the Minion Rush engine. However it seems to use all sorts of filetypes so it's tough to say if they're the same as that game. I can upload some examples if need be. I've opened up all the dats and dug out everything else thanks to whats here.

In newest game update .dat files structure was changed,and now almost every .dat file starts with RN header.
So,how i can unpack them? modifed script doesn't work
Samples in case if anyone wanna help:

The format (at least for the few I looked at) is as follows...

Code:

 -------------------------------------- 
| Spider-Man Unlimited (Android) *.dat |
 -------------------------------------- 

// ALMOST a PKZIP file, with different headers - so very similar!
// The header is "RN" for the first file, and "QL" for all other files

// FILE DATA
  // for each file
    2 - Header ("RN" for the first file, "QL" for all other files)
    4 - Unknown
    4 - null
    8 - Checksum?
    4 - Compressed File Size
    4 - Decompressed File Size
    4 - Filename Length
    X - Filename
    X - File Data
  
// DIRECTORY
  // for each file
    4 - Unknown
    2 - Unknown (20)
    2 - Unknown (10)
    4 - null
    8 - Checksum?
    4 - Compressed File Size
    4 - Decompressed File Size
    4 - Filename Length
    6 - null
    4 - Unknown
    4 - File Offset
    X - Filename
  
// ARCHIVE FOOTER
  4 - Unknown
  4 - null
  2 - Number of Files
  2 - Number of Files
  4 - Directory Length
  4 - Directory Offset
  2 - null

I'm assuming that the Compressed and Decompressed lengths are in the order above, the same as in a ZIP file.

It looks like this archive doesn't use compression, but if they want to compress any files, they actually ZIP the individual file into a normal ZIP structure, then stick that whole file in the DAT archive? For example, look at File0003.dat - the first file is a TGA image, however the file data itself starts with a "PK" ZIP header instead of actual image data, so they "zipped" up the TGA image and then stuck it in this DAT archive. The DAT archive doesn't know that it's a zipped file though - ie the DecompLength and CompLength are the same, so you'll have to read the "PK" header to know if it's actually compressed or not.

Anyone care to do a BMS for this?

I tried to take a look at file003.dat file,and i found what it have more than 1 PK entries,how i can split these entries to separate files?
Btw,is there any chance for the script? can you to do that?

here is a bms script i whipped up that works with most

Code:

for i = 0
    get CHECK long
    if CHECK == 0x07050701
        break
    elif CHECK == 0x02014b50
        break
    endif
    goto 0xe 0 SEEK_CUR
    get ZSIZE long
    get SIZE long
    get NAME_SIZE long
    getdstring NAME NAME_SIZE
    savepos OFFSET
    get CHECK2 byte
    if CHECK2 == 0x34
        string NAME - tga
        string NAME   pvr
    endif
    if ZSIZE         comtype deflate //?
        clog NAME OFFSET ZSIZE SIZE
    else
        log NAME OFFSET ZSIZE 
    endif
    math OFFSET   ZSIZE
    goto OFFSET
next i

these samples are giving problems currently, may have to adjust the script a bit
File0004.dat - png file?
File0010.dat - contains some zlib compressed data
File0023.dat - contains some zlib compressed data
may need to use first 2 bytes as ID to distinguish the compression types

Hey!

I have also bdae files (in fact bres files) in LEGO STAR WARS CASTAWAYS video game (Gameloft game). Any success with brres files? Any QUICKBMS script?

Thx for answering
