Download

Download the bundle for your system and architecture from GitHub Releases:

System	Bundle
Windows x64	5do-1.5.0-win-x64.zip
Windows arm64	5do-1.5.0-win-arm64.zip
Linux x64	5do-1.5.0-linux-x64.tar.gz
Linux arm64	5do-1.5.0-linux-arm64.tar.gz
macOS x64	5do-1.5.0-osx-x64.tar.gz
macOS arm64	5do-1.5.0-osx-arm64.tar.gz

Each bundle contains both the desktop app and the CLI. The bundles are framework-dependent: install the .NET 10 Runtime from https://dotnet.microsoft.com/download/dotnet/10.0 before running them. No .NET runtime is included in the bundle.

Extract the bundle and run the executables.

Requirements

• The .NET 10 Runtime installed on the host. The .NET 10 SDK is only needed for source builds.
• A legally obtained 3DO BIOS (1 MB; optional second 1 MB ROM for BIOS2/Kanji).
• A legally obtained disc image: ISO, BIN, CUE+BIN, or CHD.
• Windows 10+, a current Linux desktop, or macOS 12+.
• OpenGL 3.3 or GLES 3.0/3.1 for GPU presentation; a CPU fallback exists.
• No system OpenAL install is required; OpenAL Soft 1.23.1 is bundled.

Run the downloaded bundle

Windows:

.\FiveDo.Frontend.Avalonia.exe

Linux/macOS:

mkdir 5do-linux-x64
tar -xzf 5do-1.5.0-linux-x64.tar.gz -C 5do-linux-x64
cd 5do-linux-x64
./FiveDo.Frontend.Avalonia

If the extracted executable is not executable on Linux/macOS:

chmod +x FiveDo.Cli FiveDo.Frontend.Avalonia

Open the desktop app, choose Open BIOS, select a BIOS such as panafz1.bin, choose Open Disc, and press Play.

Open a disc directly:

./FiveDo.Frontend.Avalonia "Road Rash (USA).chd" --bios panafz1.bin --fullscreen

Headless CLI

./FiveDo.Cli run game.chd --bios panafz1.bin --frames 600 --frame-out frame.png

Build and run from source

git clone https://github.com/purelogiccode/5DO.git
cd 5DO
dotnet build 5DO.sln -c Release
dotnet run -c Release --project src/FiveDo.Frontend.Avalonia

Data folders

The app stores settings, NVRAM, saves, cheats, library state, and logs under the .NET local application data folder:

Windows: %LOCALAPPDATA%\5DO\
Linux:   ~/.local/share/5DO/
macOS:   the .NET LocalApplicationData location

Use Settings > Paths or About for the exact paths. Portable mode uses portable.flag, --portable, or FIVEDO_DATA_DIR.
