XTool Complete Guide

[Razor12911]

xtool v0.9.9 has added detail stream composition and graphical representation of stream and data. What you need to do is drag and drop game folder to xtool.exe whilst making sure xtoolui.dll is nearby. (Optional, if the ui dll is not present, you just get a summary and not the graphs)

We'll be using Dishonored 2 as an example.

This is the summary you get:

Processing input: E:\SteamLibrary\steamapps\common\Dishonored 2

Streams: 374562
  - zlib = 273263 (60,26%)
  - leviathan = 18 (0,01%)
  - kraken = 16 (0,02%)
  - mermaid = 1 (0,00%)
  - wwise (vorbis) = 101225 (13,48%)
  - bink (v2j) = 36 (6,66%)
  - png = 2 (0,00%)
  - bink (v1i) = 1 (0,00%)

Time: 00:02:34 (CPU 00:22:12)

Less than 1% detections can be considered false positives as this a quick scan.

and this is the graphical representation of the game.

The bar graph shaded in blue represents streams discovered in specific blocks and the line graph in green represents compression ratio for that block.

Now from here it is a question of which data type do you want to handle first, if it is the audio, you then filter the streams from the ui to see which files contain wwise audio.

You get to see what files contain audio, isolate them and use mesa or whatever tools that are available to process this audio.

Isolate the bink videos, good thing for this game they are easily identifiable by extension, isolate and process those using bpk.

And lastly, 60% of the game is zlib streams, for these you just use zlib+preflate and your job is done.
