# Project Champollion

## About this project

Rosetta 2 is an emulation mechanism to run the x86\_64 applications on Arm-based Apple Silicon with Ahead-Of-Time (AOT) and Just-In-Time (JIT) binary translation.

The technical details of Rosetta 2 are partially documented, but not rich enough.

Project Champollion is a project aimed at revealing the internals of Rosetta 2.

Currently, it provides:

- reverse-engineering results of Rosetta 2 (published in the [GitHub pages](https://ffri.github.io/ProjectChampollion/.) of this repository.)

- [analysis configurations for Ghidra](./ghidra) for analyzing AOT Mach-O binaries

- [parser of `aot_shared_cache`](./AotSharedCacheExtractor)
