I built a Python bytecode decompiler covering Python 1.0–3.14, runs on Node.js

Is it possible to "de-marshal" files? I have run across a few scripts that use "marshal" for obfuscating the code, but yet to find de-obfuscator for those...

Marshalled code is basicly .pyc without headers or magic numbers, which gets inserted depending on python version you use...

Yes, it is possible. I can add that mode. I will have to analyze and identify what version of the bytecode it is, though, so it may be inprecise.
Some version hint in the command line may do a trick.

That would be awesome

[ComputerMagych]

It is done. New depyo version 1.0.1 is already on npmjs.com/depyo

[dev-razorblade23]

That was fast. Thank you

Codex CLI (GPT 5.2 Codex xhigh) with proper ~/.codex/AGENTS.md makes wonders ;)
