Unpack Tooling for L&S Files
Atelier Lydie & Suelle game data can be unpacked using VitaSmith’s Gust Tools.
Download v1.56: https://github.com/VitaSmith/gust_tools/releases/tag/v1.56/
Lydie & Suelle Game File Location
The game install directory can be access via Steam: (Settings -> Manage -> Browse local files).
The contents should be under a path similar to this:
C:\Program Files (x86)\Steam\steamapps\common\Atelier Lydie and Suelle DX\Data
Unpacking Character Models
The file called ‘PACK00B.PAK’ contains all the character model files. It is located in “[L&S game directory]/Data/PACK00B.PAK”
To unpack this, simply drag it into the ‘gust_pak.exe’ tool provided by VitaSmith.
To ensure that your game uses the modded unpacked contents, rename the original ‘PACK00B.pak’ as ‘PACK00B.PAK.BAK’, or something to that effect.
Character Directory
The unpacked files will initially be under “[L&S game directory]/Data/data/x64/character”.
You will need to move this ‘character’ folder into the main “[L&S game directory]/Data/x64/” directory. Essentially, remove the data/data layering.
Character Model Reference
Within that “character” directory, there are models and textures for all ‘characters’ in the game. Here are the important ones:
pc50a - Lydie’s base outfit
pc50b - Lydie’s Marie outfit
pc50c - Lydie’s swimsuit outfit
pc51a - Suelle’s base outfit
pc51b - Suelle’s Ellie outfit
pc51c - Suelle’s swimsuit outfit
pc53a - Sophie’s base outfit
pc53b - Sophie’s Plachta outfit
If you are installing a mod, simply replace the original file with the provided file of the same name.
That should be all if you are installing a mod. You are done.
Contents of Models
[If you want more info…]
Each model has two core files:
pc[#+letter]_model.g1t
pc(#+letter)_model.elixir.gz
The g1t file contains the textures for the model. These can be extracted with VitaSmith’s ‘gust_g1t.exe’ tool. You may edit these and repackage these as needed.
The elixir.gz file contains the actual 3d model. These can be extracted with the ‘gust_elixir.exe’ tool.
