The Charla project at SourceForge is based off of Charla 1.6.3 by Peter Ammon (aka ridiculous_fish).

The website for the original Charla is at, there is a mirror of that site at

There are two distributions of Charla. One is headed by MysticalOS (M) and the other is headed by Thief (T). It should be obvious which distribution the file release contains, as indicated by the parentheses.

The main difference between these two distributions is in interface.

You can get the source code to either distribution at the Charla project page.
