Champollion is a decompiler for the Papyrus script language used in Skyrim, Fallout 4, Fallout 76, and Starfield. It aims to produce a Papyrus Script file (.psc) from a .pex binary file. The decompiled script should recompile to a functionally equivalent PEX binary.

Issue tracker: GitHub
Usage
Champollion is a CLI-only program.
Parameters
Starfield Warning
The decompiled syntax for the new Papyrus features in Starfield (Guard, TryGuard, Array.GetMatchingStructs) is guessed-at and should be considered unstable, experimental, and subject to change. The proper syntax will only be known in early 2024 when the Creation Kit releases, and there is a decent chance it will not match what we currently output. If you use decompiled scripts as the basis for Starfield mods, please be prepared to update them when the proper syntax is known. All lines containing guessed-at syntax will be marked with a comment starting with ';***'.
