Tom Clancy's Ghost Recon: Advanced Warfighter (Xbox 360) - Yeti.big / *.glb

What is Yeti.big and *.glb from the Xbox 360 version of Tom Clancy's Ghost Recon: Advanced Warfighter and does it contain filenames, and can someone take a look at these file formats?

The yeti file doesn't contain any file names, no. At least not that I can see.

Here's a script for the GLB files. Very easy format.

# Tom Clancy's Ghost Recon: Advanced Warfighter (Xbox 360)
# *.glb extractor

get UNK long # always 3?
get FILES long
get FOLDER basename
for i = 0 < FILES
	get NAMEL long
	getDstring NAME NAMEL
		string NAME p= "%s/%s" FOLDER NAME
	get SIZE long
	get DUMMY long # type?
	get DUMMY long # some compression identifier?
	get OFFSET long
	log NAME OFFSET SIZE
next i

For what it's worth for the .big file:

• number of files at 0x8
• TOC at 0x80, four values each it seems
  • 2-byte
  • 2-byte
  • 3-byte
  • 3-byte

Offset and size should be two of the, the other two are probably file type plus maybe some hash or crc.

Thanks for the *.glb extractor script, but how can I get filenames from yeti.big and unpack it using what debugger? DLL injection is not possible.

Sorry, such things are above my knowledge I'm afraid. The archive itself don't hold any names as far as I can see but that doesn't mean that the contents don't have internal names of course. Good luck on your venture!

Can someone make a yeti.big unpacker with proper filenames? There's no way I can restore hashed filenames from yeti.big using Xenia.
