Recently I have been trying to modify some files that are compressed with zlib. They were originally compressed with zlib 1.2.3 using Z_SYNC_FLUSH. I can decompress the original files just fine. But if I try to rebuild the files, and decompress my rebuilt ones, it fails part way through with the err...

I suppose if I had to guess too, I'd say the likelihood that VV kept the proc/md5mesh/md5anim text-based on their Doom 3 port is pretty low. :) But it's possible. Well they did keep it :) I've been working on an app and I can dump all the files and decompress them. But there are some complications....

Working on it.

Yea please upload a few. I shall do the same. I've also noticed that there are some "blank" entrys. Were the compressed size is a valid number, and decompressed size is 0. Not sure whats up with that... I'll have to play around with it some more later.

Got a semi working extractor going thanks to Anthony. But most of the extracted files don't make sense. I can see plain text strings so they decompressed correctly, but like, I have yet to see an actually asset of any kind. Somtimes I get like small <1kb files, sometimes I get these text files that ...

If you could upload the animation file I might be able to help.

Same as halo. There is a LOT to these files. So don't think you can make some script or w/e and be on your way. The tag offsets are precalculated memory addresses. There are 120 different tag layouts, that have numerous field types, references to other tags, and strings. Raw data, in the case of mod...

Xbox 360 files using lzx, I'm grabing then from my hdd right now, will make an app for it later. A little bump here... I'm just curious, how did the extraction go? Were you able to extract the archive files, and make an app for it? Completly forgot about this. I need to come up with a way to decomp...

You can dump ram. It's possible on pc and xbox. I've written a MemoryStream class in C# to do just that. It's just like a binary reader/writer except you use it with memory. For xbox, it requires some hardcore modifications and some moderate knowledge.

Lol, these files are more then meets the eye. First off this is a generic container format for xbox 360. It uses SHA1s to hash sections of data, and is all signed in the end by a RSA signiture using keys only found on your xbox 360. Luckily you can uses anyones keys since they are verifyable on fori...

The Capcome arc files are almost always the same. I have researched them in the past for dead rising. I quick check shows the formats are the same, although I'm not sure if these ones use zlib. Arc Layout Header: 0 - Magic - Chars(4) //"ARC " 4 - Version - Int16 8 - FileCount - Int16 Files...

Probally not much help, but I can tell you this is some sort of compressed image format like DXT. All I was able to locate was the height and width.

I wouldnt mind looking but all the links are expired.

Thanks, that led me to a xceed library that worked perfect!
