TitanFall (.vpk) archives

TitanFall

.VPK archives hold the game assets

Code: Select all

struct VPKDirHeader_t
{
	int32 m_nHeaderMarker;
	int32 m_nVersion;
	int32 m_nDirectorySize;
	int32 m_nEmbeddedChunkSize;
	int32 m_nChunkHashesSize;
	int32 m_nSelfHashesSize;
	int32 m_nSignatureSize;

	VPKDirHeader_t( void )
	{
		m_nHeaderMarker = VPK_HEADER_MARKER;
		m_nVersion = VPK_CURRENT_VERSION;
		m_nDirectorySize = 0;
		m_nEmbeddedChunkSize = 0;
		m_nChunkHashesSize = 0;
		m_nSelfHashesSize = 0;
		m_nSignatureSize = 0;
	}

};

The _dir.vpk files seem to have no compression however the contents do.

after installing (running through the audio decompression phase) the 8gb vpk holds the sounds as raw big endian riff data. that's as much as I can figure out.

I did some digging and found that the compression it uses is lzham Alpha 8 (you need to get it from svn). Set the dictionary size to 20. Some files aren't compressed (e.g. audio tracks).

So nice that op and other ones are lookin into this game ! I tried your program just to look around, if we are lucky depinding on your extract/pack/unpack additions we can change scripts, modify models, change the ai, many other things
Its built on the source engine, heavly modified but that means models, and script will work

Hey I tried using

Code: Select all

lzham_decompress_memory

with the uncompressed size/compressed size/dictionary size and it returns 4 as the error. Could you explain how you tried it

I actually just modified lzhamtest as a quick hack to make sure it was working. The function you're using should work just fine. Error code 4 means it failed to initialize the decompressor state, and it looks like the only way this can happen is if the params struct (called options in your screenshot) is wrong. I would check that.

Zench do you mean you are able to extract files from the packages with that hack ? :

Yes, I tested it out on a couple files. It's not really automated; instead of making it myself I figured cra0 could add it to his nice looking tool. Repacking is technically possible but probably wouldn't let you play online.

Unexpected good newsa I was thinking about porting the mechs cockpits to kerbal space program haha, been modding that game for a while, i think they would fit, esp with an robot parts mod that exits.
Cheers for trying things out =)

-EDIT-

Ok all fixed actually

will update tool in a day or so sit tight!

[kalleoskar]

Cool man!!!

[alientech]

You awesome cra0. So, This program can extract all files in one click? Because I hate to select one-by-one for extract.

[sh0ck1]

Woot! Great job cra0!

[kalleoskar]

Look forward of trying the upcoming update, thank you
