Mi az a Dolphin?

Dolphin is a GameCube and Wii emulator with high compatibility across the majority of titles for both platforms. It was first developed as closed source in 2003, and as open source since 2008.

What is Dolphin's License?

When Dolphin went open-source in 2008, it was released under the GPLv2 license. However it has since been relicensed to GPLv2+. According to the license, you may use Dolphin and its source code for any purpose, but distributing Dolphin requires that the source code be released and attribution given. For more details, see the license document.

Who Made Dolphin?

Over 200 people have worked hard over the years to create Dolphin. The list of contributors can be found on GitHub.

Dolphin is not affiliated with Nintendo in any way.

What operating systems are supported?

Dolphin is a cross-platform emulator that runs on Windows (7 and newer), Linux, and Mac OS X (Yosemite and up). For their ease of use and additional graphics backend options, Windows is generally recommended for most users. Other Unix-like systems (such as FreeBSD) may work but are not officially supported. Operating systems are required to be 64-bit to run Dolphin.

As well, Dolphin runs on Android 5.0 and up on 64-bit Android devices. The Android version of Dolphin is in alpha and should not be expected to work as well as the PC counterpart.

Which CPU should I use?

Dolphin is a dual core application that relies upon IPC (Instructions Per Clock) for performance. Additional cores will not make Dolphin go any faster, though an "extra" core that Dolphin isn’t using may help slightly by keeping background tasks from using the same cores as Dolphin.

  • Intel: Newer Core i5 and i7 processors such as the i5-4670K and i5-3570K are extremely fast and very affordable considering their relative power. The K series allows for overclocking, which can further improve the performance of those CPUs. Core i7 variants yield almost no benefit in IPC over the i5s they are based on, so save the cash if you’re building a Dolphin machine. For laptops, you can rely on the i7-4700MQ and i7-4930MX for the absolute best performance. Most games will run very well on any of those processors.

  • AMD: Due to very low IPC, AMD CPUs are poor choices for Dolphin. The FX8000 line of processors is the best they have, and even then most of those processors will be around half the speed of the 4670K’s performance with Dolphin.

Note: For more information regarding CPU performance, please checkout this handy benchmark that contains results from tons of users. Just remember that Dolphin is a console emulator: it does what the games instruct it to do. Every game has its own needs and requirements. Some games run well on most modern processors, while others won’t run full speed at all times on even the most powerful of processors.

Which GPU do I need?

Compared to processors, choosing a GPU for Dolphin is a fairly simple task. The more powerful the graphics card, the more pixels and enhancements you can throw at it before you’ll see slowdown. However, the biggest thing to watch for is making sure the GPU supports DirectX11.1 and OpenGL 4.4. Dolphin emulates a console that functions very differently from a traditional PC, and uses the latest D3D and OGL features to reduce overhead. If you do not have those extensions, performance will suffer.

  • NVIDIA: Due to the importance of the OpenGL Extension “Buffer Storage” no NVIDIA GPU before the Geforce 4xx series can be recommended. Despite being a bit old, the Geforce GTX 460 will handle almost any game you throw at it in HD resolutions. Older NVIDIA GPUs will still be able to run the games fine, especially within the D3D backend and in OpenGL with older builds still using the “Vertex Streaming Hack.”

  • AMD: Unlike the processor battle, AMD’s graphics cards actually fair very well at Dolphin. As of 4.0-1192, AMD video cards see boosts around the board because of the addition of integer math. As such, the AMD HD5770 and should run most games at HD Resolutions.

  • Intel Onboard: Intel HD3000 and HD4000 can run Dolphin at reasonable speeds, and can even run many games with enhancements; but they will struggle with demanding titles. A full fledged graphics card is highly recommended. IGPs older than the HD3000 are not officially supported.

A Dolphin működéséhez mekkora memóriára van szükségem?

2 GB vagy több az ajánlott. A memória sebessége vagy mennyisége általában nem befolyásolja az emuláció sebességét.

A Dolphin melyik változatát töltsem le?

The latest stable version of Dolphin is a good choice to start with: it works with a lot of games and is well tested. Development versions have the latest fixes and optimizations, but their constantly changing nature means that little testing has been done on them and unknown bugs may appear.

Our buildbot provides each revision of Dolphin in four variants on the main site:

  • Windows x64 for 64-bit Windows operating systems
  • Mac OS X for 64-bit Mac OS X computers
  • Ubuntu for Debian-based 64-bit Linux operating systems
  • Android APKs for 64-bit Android

Dolphin no longer supports 32-bit operating systems. To check if your version of Windows is compatible with 64-bit applications, open the Start Menu, right click on Computer and select the Properties option. A window should appear, showing "64-bit operating system" as the System type if your Windows version can run Dolphin x64. If you are running a 32-bit operating system, you should upgrade to better utilize the abilities of your hardware.

On Android, Dolphin also requires 64-bit (ARMv8 AArch64). To see if your Android phone has the necessary requirements, simply run the APK, and Dolphin will alert you.

Do note that sometimes the buildbot is not always around for a build, and various revisions may not have built correctly for all OSes. If this occurs, it will be fixed in a short time.

"This program can't start because MSVCP120.dll is missing"

If you are getting this error with a stable build, try to reinstall the application. Check that your antivirus software hasn't placed files in quarantine or deleted some of the files Dolphin needs.

If you are using a development build, extract the files from the archive to a folder on your computer instead of running Dolphin directly from inside the archive.

"This program can't start because MSVCP140.dll is missing"

Dolphin now uses Visual Studio C++ 2015 for Windows compiling, Windows users must have the 64-bit Visual C++ redistributable for Visual Studio 2015 installed in order to use development builds. The runtime has a minimum system requirement of Windows Vista SP2 and Windows 7 SP1.

Also, remember to extract Dolphin's files from the archive to a folder on your computer instead of running Dolphin directly from inside the archive.

"Az alkalmazás indítása sikertelen volt a XINPUT1_3.dll hiánya végett"

You need to install the latest DirectX runtime from Microsoft or make sure you have the latest Xbox 360 Controller Drivers installed.

"Az alkalmazás nem tudott megfelelően elindulni (0xc000007b)"

Ez a fajta hiba többnyire 64 bites Dolphin változatok használatakor jelentkezik, 32 bites használata esetén tökéletesen működik. Ha valaki észleli a vcomp100.dll vagy xinput1_3.dll hiányát jelző hiba valamelyikét, akkor általában letölti ezeknek a fájloknak a 32 bites változatát és reméli, hogy megfelelően fog működni 64 bites alkalmazásokkal.» » Amennyiben ebbe a hibába ütközöl, győződj meg arról, hogy kézileg töröltél minden letöltött DLL fájlt, a rendszer mappákból és a Dolphin telepítési helyéről, majd telepítsd azokat a megfelelő telepítő programokkal. Utalás a két fenti kérdésre a további információkért.»

My Laptop / New GPU is not performing as well as it should

Laptops and modern GPUs use a variety of tricks to reduce their power consumption and overall temperature. Underclocking, reducing voltages, using integrated instead of discrete graphics, etc. Sometimes these tricks get in the way of Dolphin, and the system needs a little help to use it's maximum capabilities with the emulator. Use the links below for assistance.

Beállítottam a gombkiosztást a második GC irányítóhoz, de mégsem működik

Győződj meg róla, hogy a GameCube 2. port Normál irányítónak legyen beállítva a GameCube fülön a főbeállítási ablakban. Ha az irányító továbbra sem működik, ellenőrizd le, hogy a játék támogat-e egyáltalán második GameCube irányítót.

How can I use my PS3 or PS4 wireless controller with Dolphin?

Install the ScpToolkit driver package to get Windows to recognize your controller as a bluetooth device, or to connect a PS3 controller to your system. They can then be used in the Dolphin GCPad and Emulated Wiimote configuration.

My audio is stuttering!

HLE Audio emulation has always been an issue for Dolphin in the past. Glitches, crashes, missing audio, volume issues, balance issues and more plagued the emulator. In an effort that eventually fixed 99% of the problems, audio emulation was revamped to be synchronous to emulation speed. This acts more like the console itself would, and prevents thousands of audio issues and crashes from cropping up.

What can you do? Well, if you’re running well below full speed, setting the frame limiter lower will get you time stretching to that framerate. The OpenAL audio backend also has the ability to timestretch regardless of what you have the framelimiter set to.

Other than that there is no solution other than to run the game full speed. If by chance you prefer buggy audio, use a version before the audio improvements, such as Dolphin 3.5.

Game "X" does not run correctly

Even with a decade of work, Dolphin isn't a perfect emulator. This means you may encounter various issues that range from minor sound or graphics defects to game breaking errors and crashes. In order to provide users with as much information as possible, the Dolphin website hosts a wiki with thousands of pages dedicated to games and various features of the emulator. Game Specific pages often list problems a game has, solutions, and what settings are needed to make it run as accurately as possible.

If you find a bug in a game that isn't listed on the Wiki, please checkout the issue tracker and see if it is reported there. If it isn't, feel free to report the bug you found so that the developers are aware of the issue. Be aware, one of the rules you must follow before reporting an issue is make sure the issue isn't already fixed on the latest development version.

Dolphin speeds up when I open the graphics menu?

Dolphin is configured to run as fast as possible by default. However, for some games, that will cause a lot of problems, and they need more accurate and more demanding settings to run properly. For user convenience, many games have had these settings preconfigured in the "GameINI", a file with custom settings for each game.

By opening the graphics menu, you are overriding the GameINI default settings and instead using the settings within the graphics menu, which will be the global defaults or whatever you last set them to. If you are playing a game that needs accurate but demanding settings, opening the graphics menu will disable those settings and result in a speed up. However, you will then be subject to the glitches and problems the GameINI settings were protecting you from.

See the Dolphin Wiki for details on what games needs which settings to run correctly and why.

The build instructions are available on GitHub:

Mi a legjobb módja a fejlesztés figyelemmel követésének?

Builds are compiled for every development version of Dolphin and are available on the download page.

All of the Git commits are also available on GitHub where you can comment on changes and view new pull requests to get a jump on upcoming features.

Van ötletem a Dolphin javítására, hogyan juttathatnám a fejlesztők tudomására?

Most of the Dolphin developers read the "Development discussion" forum. Posting a thread there might be a good idea to get some feedback from developers but also from users.

Dolphin developers also communicate via IRC, which is better for instant discussion than a forum. Join us on #dolphin-emu @ irc.freenode.net.

Even if your idea is very good, note that developers are doing their work on Dolphin on their free time and don't necessarily have the time to implement everything people suggest. If you can, implementing a first draft of your idea might be a good way to get developers attention.

Nem használhatna a Dolphin több magot a processzorból, hogy gyorsabban működjön?

CPUs do not work that way.

Every core on a CPU runs in parallel. Two tasks can run very well in parallel if they don't need to communicate often or to run at the exact same speed. For example, compressing files can be run on separate cores because compressing one file and compressing another file are two completely independent tasks, which do not need to communicate.

In Dolphin, the only demanding tasks that can run well in parallel are the CPU, the GPU and the DSP. Breaking up any of these tasks into smaller tasks just to run it on more cores is very likely to make the program slower. That's why Dolphin only runs on 3 cores and won't use all of your 4 or 6 cores CPU.

Miért van ilyen erős gépre szükség egy régi konzol emulálásához?

While it's true the GameCube and Wii hardware is a lot slower than what you need to emulate the console using Dolphin, the hardware found in these consoles is also very different from what you can find in a gaming PC. For example:

  • Instead of an Intel or AMD x86 CPU, GameCube and Wii use an IBM PowerPC CPU. Games are programmed for this CPU: when emulating, every basic instruction a game runs needs to be translated to something a PC can execute. Depending on the instruction, this can take from 2x to 100x clock cycles, which explains why you need more than a 486MHz CPU to emulate a GameCube.

  • The RAM in these consoles is SRAM, smaller but faster than the SDRAM used in a PC. It is also shared between CPU and GPU, which makes operations like texture uploads (CPU memory to GPU memory) or framebuffer copies (GPU memory to CPU memory) a lot less demanding than they are on a PC.

  • The GPU is not using shaders: every graphics effect and every computation done by the game is executed directly by the hardware without an intermediate programming language. This does not match how a PC GPU works at all. Dolphin uses shaders on the PC GPU to translate what the GC GPU can do directly in hardware, causing it to run a lot slower.

  • A PC runs an operating system in order to be able to run several programs at the same time. A GameCube or a Wii does not have the same requirement and can directly execute things on the hardware without going through the operating system, making a lot of communication between chips faster.

This list is not exhaustive but should give you a good idea of what exactly makes emulation require a powerful computer.

Honnan tölthetnék le játék ISO/ROM fájlokat?

Rövid válasz: Sehonnan. Vásárolj meg játékokat és készíts róluk másolatot Wii konzollal.

Hosszabb válasz: Kereskedelmi játékok letöltése jogellenes, ezért azt a Dolphin fejlesztői teljes mértékben elítélik. Ezáltal kívánnak tartózkodni a jogi vitáktól, mint azok a homályos részek, hogy olyan játékok letöltése amiket korábban megvásároltál. Nincs szükséged saját játékkonzolra, mert ha megvásárolsz egy játékot, akkor készíthetsz róla saját másolatot valamelyik barátod konzolján is. Másrészt, a barátod játékmásolatainak lemásolása is törvényellenes.

Wii konzollal történő játékmásolatok készítéséhez, telepítened kell a Homebrew Channel programot és használni a következő alkalmazást: CleanRip.

Milyen képfájlokat támogat a Dolphin?

Dolphin supports playing games dumped in the following formats:

  • GCM/ISO (uncompressed dumps, should be 1.4GB for GameCube games and 4.7GB for Wii games
  • GCZ (Dolphin can be used to compress your games to this format)
  • CISO
  • WBFS (not supported in Dolphin 3.0 or earlier)

Note that WBFS and CISO are lossy compression formats: they remove some of the unused information stored on the discs to make files smaller. As such, we recommend you try dumping your games as GCM/ISO if you get issues using a WBFS dump.
