A dual-screen mod of the Pokémon Emerald decompilation for the AYN Thor and other dual-screen Android devices. The game runs natively, no emulator involved.

No ROM or copyrighted assets are included. Provide your own Pokémon Emerald (USA/Europe) ROM to get the game up and running. This is meant to be a vanilla dual-screen experience; ROM hacks aren't supported.

Getting started

1. Install the APK from the latest release.
2. Launch the app and tap Select ROM when asked, then pick your Pokémon Emerald (USA/Europe) ROM.
3. That's it. The app restores the game data once and boots straight into the game. Future launches skip this step.

You can bring an existing save with you. Any ordinary 128 KB GBA flash save (.sav or .srm), the same file an emulator or a cartridge dumper writes, can be imported. This doesn't include savestates or other formats. See install and saves for the steps.

Guide	Description
Install and saves	Installation, updates, save imports and backups.
Settings	Display, controls, sound and 3D options.
Build from source	Build your own Android APK.
Run on PC	Run the Android app in a dual-screen emulator.
