Commit: b198c08defb94081ae995796cf75ab8cdb51f2d0
Existing Emerald source data: https://github.com/pret/pokeemerald/tree/731ad5bfd6e6f265508d0efcca0ba42f9dcf5881

The models and terrain are exported by the original Emerald 3DS generators and host C scene builder. Building and terrain textures derive from the existing Pokémon Emerald source graphics. The voxel tree textures are original Emerald 3DS artwork. The original licenses below cover port code and its original contributions; they do not relicense Pokémon Emerald game content. Pokémon and its game graphics remain the work of Nintendo, Game Freak and Creatures. Cinderwild adds a browser export adapter and retains its existing campaign navigation and real-time battles.

# Emerald 3DS port licence

## Scope

The licence below applies **only** to original Emerald 3DS port code, tooling
and documentation authored for this project: the contents of `3ds_port/`,
`builder/`, `tools/` and `docs/`, and the port's own additions inside
`patches/pokeemerald/`, unless a file states otherwise.

It does **not** relicense:

- Pokémon Emerald, its code, data, graphics, audio, text or any other content;
- the [pret/pokeemerald](https://github.com/pret/pokeemerald) decompilation,
  including the upstream lines that appear as context in the patches;
- data generated from a ROM (such as `emerald3ds.pak`);
- third-party components, which keep their own licences (see `NOTICE.md`).

A modified upstream file is covered here only for the Emerald 3DS
contribution to it.

What was reused is the *logic*: map instance construction, metatile
classification, the 512x512 metatile atlas composition and the follow camera.
