Slippi Mainline

This is a WIP effort to port the functionality of https://github.com/project-slippi/Ishiiruka to mainline Dolphin. Currently, we are nearly even with master upstream and close to on par with project-slippi/Ishii upstream. Last updated 12/02/2020

How can I contribute?

Dolphin - A GameCube and Wii Emulator

Homepage | Project Site | Buildbot | Forums | Wiki | GitHub Wiki | Issue Tracker | Coding Style | Transifex Page

Dolphin is an emulator for running GameCube and Wii games on Windows, Linux, macOS, and recent Android devices. It's licensed under the terms of the GNU General Public License, version 2 or later (GPLv2+).

Please read the FAQ before using Dolphin.

System Requirements

Desktop

• OS
  • Windows (10 or higher).
  • Linux.
  • macOS (10.15 Catalina or higher).
  • Unix-like systems other than Linux are not officially supported but might work.
• Processor
  • A CPU with SSE2 support.
  • A modern CPU (3 GHz and Dual Core, not older than 2008) is highly recommended.
• Graphics
  • A reasonably modern graphics card (Direct3D 11.1 / OpenGL 3.3).
  • A graphics card that supports Direct3D 11.1 / OpenGL 4.4 is recommended.

Android

• OS
  • Android (5.0 Lollipop or higher).
• Processor
  • A processor with support for 64-bit applications (either ARMv8 or x86-64).
• Graphics
  • A graphics processor that supports OpenGL ES 3.0 or higher. Performance varies heavily with driver quality.
  • A graphics processor that supports standard desktop OpenGL features is recommended for best performance.

Dolphin can only be installed on devices that satisfy the above requirements. Attempting to install on an unsupported device will fail and display an error message.

Build Process

Dolphin requires CMake for all systems. Many libraries are bundled with Dolphin and used if they're not installed on your system. CMake will inform you if a bundled library is used or if you need to install any missing packages yourself.

Rust

This fork includes a Rust submodule that needs to be built and linked to the final executable. This means that you will need to install a Rust compiler for your current system; to do this, simply visit rustup.rs. Once installed, CMake should be able to automatically handle the rest for you.

Windows

Visual Studio 2019 16.3 or later is a hard requirement. Open the folder that contains the base CMakeLists.txt file to build Dolphin on Windows. Other compilers might able to build Dolphin on Windows but have not been tested and are not recommended to be used. Git and Windows 11 SDK must be installed when building.

Make sure to pull submodules before building:

git submodule update --init

The "Release" solution configuration includes performance optimizations for the best user experience but complicates debugging Dolphin. The "Debug" solution configuration is significantly slower, more verbose and less permissive but makes debugging Dolphin easier.

An installer can be created by using the Installer.nsi script in the Installer directory. This will require the Nullsoft Scriptable Install System (NSIS) to be installed. Creating an installer is not necessary to run Dolphin since the Binary directory contains a working Dolphin distribution.

macOS Build Steps:

A binary supporting a single architecture can be built using the following steps:

1. mkdir build
2. cd build
3. cmake ..
4. make -j $(sysctl -n hw.logicalcpu)

An application bundle will be created in ./Binaries.

A script is also provided to build universal binaries supporting both x64 and ARM in the same application bundle using the following steps:

1. mkdir build
2. cd build
3. python ../BuildMacOSUniversalBinary.py
4. Universal binaries will be available in the universal folder

Doing this is more complex as it requires installation of library dependencies for both x64 and ARM (or universal library equivalents) and may require specifying additional arguments to point to relevant library locations. Execute BuildMacOSUniversalBinary.py --help for more details.

Linux Global Build Steps:

To install to your system.

1. mkdir build
2. cd build
3. cmake ..
4. make -j $(nproc)
5. sudo make install

Linux Local Build Steps:

Useful for development as root access is not required.

1. mkdir Build
2. cd Build
3. cmake .. -DLINUX_LOCAL_DEV=true
4. make
5. ln -s ../../Overwrite/{Sys,User} Binaries/

Linux Portable Build Steps:

Can be stored on external storage and used on different Linux systems. Or useful for having multiple distinct Dolphin setups for testing/development/TAS.

1. mkdir Build
2. cd Build
3. cmake .. -DLINUX_LOCAL_DEV=true
4. make
5. cp -r ../Overwrite/{Sys,User} Binaries/
6. touch Binaries/portable.txt

Building for Android

These instructions assume familiarity with Android development. If you do not have an Android dev environment set up, see AndroidSetup.md.

Make sure to pull submodules before building:

git submodule update --init

If using Android Studio, import the Gradle project located in ./Source/Android.

Android apps are compiled using a build system called Gradle. Dolphin's native component, however, is compiled using CMake. The Gradle script will attempt to run a CMake build automatically while building the Java code.

Uninstalling

On Windows, simply remove the extracted directory, unless it was installed with the NSIS installer, in which case you can uninstall Dolphin like any other Windows application.

Linux users can run cat install_manifest.txt | xargs -d '\n' rm as root from the build directory to uninstall Dolphin from their system.

macOS users can simply delete Dolphin.app to uninstall it.

Additionally, you'll want to remove the global user directory if you don't plan on reinstalling Dolphin.

Available DSP emulation engines are HLE (High Level Emulation) and LLE (Low Level Emulation). HLE is faster but less accurate whereas LLE is slower but close to perfect. Note that LLE has two submodes (Interpreter and Recompiler) but they cannot be selected from the command line.

Available video backends are "D3D" and "D3D12" (they are only available on Windows), "OGL", and "Vulkan". There's also "Null", which will not render anything, and "Software Renderer", which uses the CPU for rendering and is intended for debugging purposes only.
