Gameloft GLLib/Ice Age Vlillage (2009[?]-?Extensionless files)

Post by LolHacksRule »

I want to view Ice Age Village's assets but they are likely ALL packed in separate parts in each of the the extensionless files and they are possibly encrypted or compressed uniquely, any advice on trying to read this or will someone try? If so thanks a lot. http://www.filedropper.com/iceagevillag ... nlessfiles, 5 is a broken archive asking for a password when repairing it, encrypted for sure...

UPDATE: This isn't specific to C.O.R.E.

Oh ok. Guess I'd better assume that for all old GameLoft games...

Quick bump, the script doesn't work on the file named "999". Does it have data or is it metadata or something similar? http://www.filedropper.com/iavbase Some files here also don't work, 20XXX is audio.

UPDATE: it is

Code: Select all

Can't read 1 bytes from offset 01300000.
       Anyway don't worry, it's possible that the BMS script has been written
       to exit in this way if it's reached the end of the archive so check it
       or contact its author or verify that all the files have been extracted.
       Please check the following coverage information to know if it's ok.

  coverage file 0    41%   298        714        . offset 01300000

Last script line before the error or that produced the error:
  17  get FLAGS byte  # 0x81

There's a bunch of tools in this repo for this format. https://github.com/bartlomiejduda/Tools ... 0Unleashed

A portion of the files in Ice Age Village's archive titled 21, appear to be encrypted... Most likely these are parameters, according to an older version of the game with symbols (which is likely similar to the final release, as releases beyond 3.3.2 has stripped them [at least on Android]), these are XOR encrypted. Functions by various load functions call for DECODE_XOR32 to decrypt a file and also deserialize certain files. Can someone decrypt these if possible?

Very late rebump but would detection of files split with a approximate size of 1,048,576 be implemented? For example 9000 and 9001 being that size with 9003 to end the full file or will I have to manually modify the files to fix the related data? It's why a few files in Ice Age Village fail to extract on my end. Also the related XOR key for encrypted files appears to be 7FA1E9 (or 7FA1E8) but I still can't get readable data.
