Atelier Tools

Tools and libraries for Atelier games by Gust.

Functionality will likely be limited to PC versions of modern Atelier games that I own.

Functionality

• .pak decoding:
  • Atelier Sophie DX
    • Atelier Sophie DX Artbook
  • Atelier Firis DX
    • Atelier Firis DX Artbook
  • Atelier Lydie and Suelle DX
    • Atelier Lydie and Suelle DX Artbook
  • Atelier Ryza
  • Atelier Ryza 2
  • Atelier Sophie 2
  • Atelier Ryza 3
• .g1t parsing for most formats
• DDS decoding:
  • Texture formats:
    • RGBA8
    • BC1/DXT1
    • BC3/DXT5
    • BC6H
    • BC7

g1t texture support:

• Atelier Sophie: 1725/1725 (100.0%) textures supported
• Atelier Firis: 2645/2648 (99.9%) textures supported
• Atelier Lydie and Suelle: 5176/5178 (100.0%) textures supported
• Atelier Ryza: 2194/2197 (99.9%) textures supported
• Atelier Ryza 2: 2941/2949 (99.7%) textures supported
• Atelier Sophie 2: 3284/3295 (99.7%) textures supported
• Atelier Ryza 3: 6270/6290 (99.7%) textures supported

Goals

• Be easier to understand than gust_tools
• Be usable as a library
• Support unpacking enough file types to create a decent auto-generated wiki
• (ideally) be faster than gust_tools

Anti-goals

• Be a complete replacement for gust_tools: This project is (currently) not focused on encoding external assets to be used in the game, it only tries to read these assets or convert them to usable formats.
• Support every single format and every single game: This project was born to support atelier-wiki (as to not need any C dependencies) and because I thought it was a fun project. As such, I won't try to support every Atelier game ever made, and I'm unlikely to accept pull requests for games I don't personally own.
