Nfs Most Wanted Bin Files
« on: February 08, 2006, 09:39:00 PM »

From what I know about the files from the xbox demo of the game (haven't looked at the files of the final game), there are are bunch of ZZDATA files and a ZDIR file. The ZZDATA files contain raw data of every file needed by the game without any header or structure to them aligned in 2048 byte blocks, and the ZDIR file contains the information on which ZZDATA contains which file, where and how many blocks it takes. Many other games (especially PS2 versions) from the same developer use this storage format.

However, there is a problem here... normal ASCII strings are not used to represent the filenames in the ZDIR -- they use a one way hash. It's not computationally feasible (read: almost impossible) to derive the filename from the hash, so you're pretty much screwed unless you want to go through every possible block of data in the ZZDATAs and figure out what kind of file it is. Not worth the effort imho.

Hmm, they sure have made it hard, or at least sound extremely difficult!

Damn them...
