An OnionOS port of Stardew Valley for the Miyoo Mini and Miyoo Mini Plus.

Stardew Valley and its assets are not included. Compatibility build 1.6.15.24356 is supported.

The setup app can sign in to Steam with a Steam Mobile QR code, download the supported compatibility build and prepare the OnionOS package. You do not need to find or download a depot yourself.

If setup fails, open Show log in the app and use Copy or Save when reporting the problem.

Download the setup app for Windows, macOS or Linux from the release page. Debian and Ubuntu packages are available as .deb files too.

For command-line setup, use the prepare.sh script described below.

The app uses Mono 6 and Docker to build the device-specific game files. On Windows, both tools must be available inside WSL.

1. Own Stardew Valley on Steam and sign in to the Steam desktop client.

2. Open steam://open/console in a browser.

3. For 1.6.15.24356, run:

   download_depot 413150 413151 4848991934266309406
   

4. Steam prints the download location when it finishes.

1. Download the release archive and extract it.
2. Copy the downloaded depot into the release's gamefiles folder.
3. Install Mono 6 and Docker.
4. Run ./prepare.sh from the extracted folder. On Windows, run it in WSL.
5. Copy OnionOS-package/Roms to the root of the Miyoo SD card.

Another compatibility build can be tried with ./prepare.sh --allow-untested-build. The script will still check the file layout, relinker and save serializers, but it cannot confirm that the game will work on the Miyoo Mini. Untested builds do not use serializer AOT and do not need Docker.

On Windows, install Ubuntu from PowerShell with wsl --install -d Ubuntu and open Ubuntu once to finish its setup. In Ubuntu, run sudo apt update && sudo apt install mono-devel. Then enable Ubuntu under Docker Desktop's WSL integration settings. The docker-desktop distribution is Docker's internal environment; do not try to install Mono in it.

The copy of prepare.sh under release-tools is here for review. Use the one in the release archive; it needs files that are only shipped with the release.

The port appears in OnionOS as Stardew Valley for Miyoo Mini.
