About Kolto Labs

Kolto Labs is an independent, non-commercial fan project. We build tools for Star Wars: Knights of the Old Republic and Knights of the Old Republic II: The Sith Lords.

Our main project is Kolto Tank: KotOR in your browser, with a library of mods and extensions, a full debugger and TAS tools. It's in development and not open to the public yet. You bring your own copy of the game.

We also release smaller tools. kq lets you query a game install from the command line, and kotor-formats is a set of shared Rust libraries for the games' file formats. Both are released.

The name comes from kolto, the healing medium harvested in the oceans of Manaan. The games are more than twenty years old, and people still mod them.

Keep the games moddable for the next twenty years.

Kolto Tank is meant to give modders one place to publish and players one place to run mods. The plan is for mods to run in the browser, so a modder's files stay under their control and players get updates without reinstalling. We also want the games on phones, tablets and TVs. None of that works yet.

The tools under it follow one rule: load a file, save it unchanged, get the same bytes back. Parsers are strict by default and lenient only when you ask.

• Each released project has one repository, under github.com/kolto-labs.
• Bugs and feature requests go in public issues.
• Our released projects are MIT-licensed.

The games never shipped with public documentation or an official modding toolset. Modders mapped the engine themselves, and that work produced TSLPatcher, KotOR Tool, DeNCS and two decades of mods. We build on it and credit it.

We work with games we own. We never commit game assets or original executables. Kolto Tank doesn't include the game either: you link your own copy from Steam, GOG or Amazon, or upload your own files.

We're not affiliated with Lucasfilm, BioWare, Obsidian or the games' publishers. Is it legal? Yes. We build interoperable tools for games people already own, and we ship none of the games' content.
