If you want to convert a file or a hex dump in multiple formats you can find other tools in that same page (like byte2c, hex2byte, byte2hex and so on).

Anyway if somebody is curious, the format is the following: 4 bytes = number of files (the final is NULL, just a delimiter due to the method used for calculating the file size (next_offset - prev_offset)) for each file: 4 bytes = absolute offset X bytes = filename, NULL terminated little endian form...

Why don't you just tell all of us first what the method for encoding is, and THEN write a decoder for him? I have seen you lurk at this forum for a long time (you may be invisible to others, but not to me) and you refuse to help people here. Tread lightly, friend. Agree with you. Personally I hate ...

For help on LZO, try to use minilzo (available on the same website): len = lzo1x_decompress_safe(in, len, out, outsz, LZO1X_MEM_DECOMPRESS); where in is the buffer containing the compressed data, len is the lenght of this data, out is the output buffer which will contain the decompressed data and ou...

Rahly: will this tool be open source and portable to other platforms other than Win32? About the question of Strobe, making that type of program (search using xor, plus, less and other operations) is very simple but how many programs use these simple types of encoding and how we know what keyword to...

I have seen the new section in the wiki and it is really excellent 8-) Having all the "strange" compression/encryption algorithms collected and documented in one page is really useful. I have found only one problem while I wanted to add the .tntfolder and some other formats to the page, in...

Excellent idea. I admit that I have started to watch more deeply the audio formats (algorithms) only in the last days so I'm still a newbie in this field. Let's start with some links. Xbox ADPCM: Used for some of the audio data contained in the XWB archives available mainly on the Xbox console for g...

I didn't resist and wrote a xbox adpcm to wave converter 8-)

So also the users of any other operating system can hear this files.

I wrote an extractor many time ago:

(search "eve online")

That's bad, means the game uses encryption or other types of compression. Unfortunately only zlib and another small number of libraries allows to know if a piece of data is correctly compressed with that algorithm. I have written a simple tool which uses many algorithms for unpacking data but it can...

Comparing 2 executables is not so simple, but I think that the first step is being sure that the executables are in plain-text (aka not encrypted/compressed) so you must launch them and dump the process memory (although this is probably not enough with some rare strongly encrypted files). Then you m...

If something is compressed with zlib within the file you can check it by yourself with Offzip: http://aluigi.altervista.org/mytoolz.htm#offzip create a temp folder and then type: offzip -a yourfile.dat temp 0 and if finds nothing: offzip -z -15 -a yourfile.dat temp 0 (the tool supports also other se...

and I'm pretty sure it's some form of 4bit ADPCM compression, but then I'm completely stuck. I've tried running the data through Benjamin Haisch's xbox adpcm decoder and I've tried to decode it using a PS2 adpcm decoder, but both gave pretty useless output files. Any ideas/insights/help are/is welc...

As far as I know exist tons of ADPCM algorithms, about what you refer?

No good news, unfortunately.
I have just finished that experimental program (about 23 compression algorithms supported at the moment) and have found nothing about the compression used by the game.
