📋 About This Mod
A tool to decompile a . PEX file to a recompilable . PSC script file.
Champollion is a command-line utility that decompiles Skyrim's compiled .PEX script files back into editable .PSC source code, allowing modders to reverse-engineer and modify existing scripts. With over 7,000 endorsements and 466,000 downloads, it's a proven tool for the modding community, though it hasn't been updated since 2013.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Community staple for Skyrim modding—7,224 endorsements and nearly half a million downloads prove it's the go-to for script decompilation
- Essential for reverse-engineering mods or recovering lost source code, saving hours of manual rewriting
- Lightweight and command-line based, so it's fast and scriptable for power users
⚠️ Cons
- No updates since April 2013—might have issues with newer Skyrim versions or special edition, though the core format hasn't changed much
- Command-line interface might intimidate casual modders who prefer GUI tools
- No documentation or usage examples provided in the description, so you'll need to figure out the syntax yourself or find community guides
For Skyrim mod authors who need to decompile .PEX files to edit or learn from existing scripts. Also for players who want to tweak mod behavior by modifying scripts directly. Skip if you're not comfortable with command-line tools or don't plan to dig into script-level modding.
💡 Beginner Tips
- Run the tool from the command line with the .pex file as an argument—it will output a .psc file in the same directory
- Use the decompiled .psc as a reference for learning Papyrus scripting, but be aware that decompiled code may not be perfectly clean
- If you're modding Skyrim Special Edition, test the output carefully as the tool predates SSE and may need tweaks
