Where the device has VK_EXT_extended_dynamic_state, the cull mode and the depth test, write and compare function of a GX or ubershader pipeline are set per draw, and pipelines that differ only there are one VkPipeline: a pipeline asked for whose shaders, vertex layout, blending, topology and framebuffer match one already built takes that one at once instead of being compiled. Fewer pipelines are compiled, in the background and on the spot alike. The shared pipelines sit in a fixed open-addressed table every thread building pipelines reads and adds to without a lock, counted by the pipelines using them; a shader is told apart by a number given it when it is made, not by its address. The state tracker sets only what differs from what the command buffer has set already, and sets it again after a pipeline with the state built in. The colour blend attachments of a pipeline are kept on the stack.
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 1903 or higher).
- Linux.
- macOS (11.0 Big Sur 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 (7.0 Nougat 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.
Building
This tree builds the parallel_gamecubewii libretro core with the static Makefile. Pull all submodules first:
git submodule update --init --recursive
Then run make from the top of the tree. Linux, macOS and Windows (MSYS2, any
environment) are detected; other targets take platform=:
| Target | Command | Output |
|---|---|---|
| Linux, webOS | make |
parallel_gamecubewii_libretro.so |
| Windows (MinGW-w64) | make |
parallel_gamecubewii_libretro.dll |
| macOS | make |
parallel_gamecubewii_libretro.dylib |
| iOS | make platform=ios-arm64 |
parallel_gamecubewii_libretro_ios.dylib |
| tvOS | make platform=tvos-arm64 |
parallel_gamecubewii_libretro_tvos.dylib |
| Android | make platform=android-arm64 (or android-x86_64), NDK from ANDROID_NDK_ROOT |
parallel_gamecubewii_libretro_android.so |
Cross builds pass the compilers, e.g. make CC=aarch64-linux-gnu-gcc CXX=aarch64-linux-gnu-g++.
DEBUG=1, LTO=-flto and SANITIZER=address,undefined are available everywhere.
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.
Command Line Usage
Usage: Dolphin.exe [options]... [FILE]...
Options:
--version show program's version number and exit
-h, --help show this help message and exit
-u USER, --user=USER User folder path
-m MOVIE, --movie=MOVIE
Play a movie file
-e <file>, --exec=<file>
Load the specified file
-n <16-character ASCII title ID>, --nand_title=<16-character ASCII title ID>
Launch a NAND title
-C <System>.<Section>.<Key>=<Value>, --config=<System>.<Section>.<Key>=<Value>
Set a configuration option
-s <file>, --save_state=<file>
Load the initial save state
-d, --debugger Show the debugger pane and additional View menu options
-l, --logger Open the logger
-b, --batch Run Dolphin without the user interface (Requires
--exec or --nand-title)
-c, --confirm Set Confirm on Stop
-v VIDEO_BACKEND, --video_backend=VIDEO_BACKEND
Specify a video backend
-a AUDIO_EMULATION, --audio_emulation=AUDIO_EMULATION
Choose audio emulation from [HLE|LLE]
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.
