Dolphin is a Nintendo GameCube and Wii emulator, currently supporting the x86_64 and AArch64 architectures. Dolphin is available for Linux, macOS, Windows, and Android. It is a free and open source, community-developed project. Dolphin was the first GameCube and Wii emulator, and currently the only one capable of playing commercial games.
Install one of the following:
- Dolphin emu — A GameCube / Wii emulator
- Dolphin emu (git) — A GameCube / Wii emulator (development version)
While no additional configuration is needed for the emulator to run (it is preconfigured with the default settings), altering the settings can improve performance and graphics alike. Settings are split to three main sections, Config, Graphics and DSP.
On the General tab, check Enable Dual Core and Enable Idle Skipping. The frame limit should be set to "Auto", so that it works with games from all regions. The CPU emulation engine should be left as JIT Recompiler. Only check "Force console as NTSC-J" if intending to play imported Japanese discs.
All options on the "Interface" tab are personal choices.
The Audio tab is the DSP section's screen; setting it up now means there will be no need to do it later. See the DSP settings paragraph below.
The next two tabs are not very important; the Gamecube tab has settings about connected accessories, such as memory cards, and the only remarkable Wii tab option is the "Aspect Ratio" drop-down list. Set it to either 16:9 or 4:3, depending on the display's aspect ratio.
On the final tab, "Paths", ISO directories can be set. The directory of game ISOs can also be set by clicking browse from the home screen, but here more options are available, such as Search Subfolders.
On the "General" tab, choose OpenGL from the backend drop-down list. Set the "Display" and "Other" settings to the desired configuration. V-sync is useful, but it can lead to slowdowns. The "render to main window" option improves the experience aesthetically.
On the "Enhancements" tab are the options that can improve graphics. While they result to great output, they can slow the emulation down to the point of making games unplayable. Choose the best settings possible, as long as speed remains 100%.
|Internal resolution||1x Native||Auto (Window size)|
|Anti-aliasing||None||at least 2x|
|Anisotropic filtering||1x||at least 2x|
|Post-Processing Effect||(off)|| your choice|
(see tip below)
|Scaled EFB copy||unchecked||checked|
| Force texture filtering,
|off|| your option|
Unless sure, the Hacks tab is best left untouched.
|Skip EFB access from CPU||unchecked|
|Ignore format changes||checked|
|Texture cache/ Accuracy||Fast|
|External frame buffer||disable|
|Cache display lists||unchecked|
|Disable destination alpha||unchecked|
|OpenCL texture decoder||unchecked|
|OpenMP texture decoder||unchecked|
|Fast depth calculation|| checked|
(Should uncheck for anaglyph 3D)
|Vertex streaming hack||unchecked|
Similarly, unless sure, leave everything in the Advanced tab unchecked.
Set the DSP emulation engine to
- DSP HLE for speed over accuracy,
- DSP LLE recompiler for better accuracy with the cost of some speed,
- DSP LLE interpreter; accurate but makes everything unplayable. Too slow.
DSP LLE on separate thread improves speed on computers with multi-core CPUs, but might cause audio glitches, and is known to break Zelda ucode games. Audio backend is best set to ALSA. For
pulseaudio, Dolphin's optional dependency PulseAudio needs to be installed.
Click on browse to set a directory of ISOs so that they are shown as a library on Dolphin's default screen. Otherwise just click Open and select the file.
Whenever a game doesn't work properly, try reading its page on Dolphin's wiki. Listed there are tips on setting up the emulator for each game, version compatibility charts, testing entries, troubleshooting and video previews. Contributions, such as testing entries and workarounds are welcome and help other users.
Here's asearch action command for searching on Dolphin's wiki:
exo-open --launch WebBrowser https://wiki.dolphin-emu.org/index.php?search=%u
Incompatibility with Wayland
Dolphin 5.0 is not compatible with Wayland. Force it to run as X11 application via this command:
Launching games fails with "WriteRest Op" error
Add "-fno-pie" to "CXX_FLAGS" when building Dolphin.
Games play too fast
Make sure the framelimit is set to a proper value for the game's region; 60 for NTSC games or 50 for PAL ones. Auto is recommended. Avoid playing other media simultaneously with Dolphin.
Emulation is too slow
Double-check the CPU scaling governor. If using an NVidia graphics card, on nvidia-settings changing the powermizer setting to "Prefer maximum performance"; check its temperature to make sure the card does not overheat, though. Change Dolphin's priority using nice. Killing unnecessary processes and disabling compositing also helps. Configuring Dolphin correctly, as described above, is the most important part.
Many systems have more than one GPU, like an integrated low-performance one by Intel and a dedicated graphics card. Run
DRI_PRIME=1 dolphin-emu to execute Dolphin on your dedicated GPU. See PRIME for details.
