About

A decompilation that reconstructs the European base release of Pokémon Moon from its Nintendo 3DS ARM executable, with source code, build tooling, symbol metadata and reverse engineering notes. The manifest records 2,984 source-backed functions out of 18,945 inventoried internal functions (15.75%). It contains no retail game binaries or assets, and also provides a separate portable PC runtime target using SDL2 and OpenGL.

Getting started

You must provide files extracted from your own legally obtained copy of the game, placed in the expected local paths. The PC runtime is built separately with CMake and reads retail resources from an external data folder.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Nintendo 3DS version).

Retail resources must be supplied externally under a selected data root.

Features

A native PC runtime uses SDL2/OpenGL for input and rendering and shares reconstructed game logic.

How to install

Run the PC executable; use `--headless` to start without a window.
Select external game data with `--data-root`, `POKEMOON_DATA_DIR`, or `POKEMOON_DATA_ROOT`.
