Dolwin is an open-source Nintendo GameCube emulator which initially started development in 2004. It went into hiatous but is now active. With that in mind, it's not the most advanced but has interesting features and is able to boot and run some commercial games and demos.

  • Emulation requires DSP IROM / DROM dumps

  • A BIOS image dump is not required, but if you want to experiment with it, you can also add it in the settings. The BIOS is launched through the menu File -> Run Bootrom. Then you need to wait a bit and open the drive cover (File -> Swap Disk -> Open Cover). After that, IPL Menu will start :p


Build using Visual Studio 2019.  To build, open Dolwin.sln and click Build.

The executable will be at the root (Dolwin.exe).

CPU: Desirable that your processor contains 4 cores+


Most Recent Changes

Fixed a nasty bug with restarting.

Show Previous Changes


The release work was evenly spread over previous releases, but the bulk of the new DSP core was implemented in this version.

For example, Luigi's Mansion now comes to the forest scene.

PS. Also keep in mind that there is a nasty bug exists - after starting the game, you need to restart the emulator every time --(Dolwin.exe)


This release is the beginning of work on improving the graphics system.

A new component has been added to the emulator - GX, which contains the general code for emulating the command processor (CP)

Old DolwinVideo code has been cleaned up from old stuff. It is still used as a reserve parachute until a more advanced backend appears.

In parallel, improvements have been made in DSP emulation, but there is still a lot of work to be done in this area

Fixed minor bugs that got out after splitting the emulator core and user interface.

Some games show slight progress: Luigi's Mansion now shows 1 screen further from the main menu, and Wario Ware even reaches the game, but with big slowdowns and graphical bugs. You can even hear how Wario is unhappy with this circumstance (there is sound in the game).


This is the first attempt at porting Dolwin to Linux-like operating systems.

Let me remind you that Playground is a "smaller" version of Dolwin, without a graphical interface and with Null backends (that is, no graphics, sound, etc.). All that is visible to the user is the emulator debug messages.

Porting was done in WSL2 environment on Windows, Ubuntu version 18.04.


Intermediate release related to source code refactoring. It was decided to make the emulator cross-platform.

Now the whole core is in a separate executable module (for Windows it is DolwinEmu.dll), and the user interface and debugger in the main executable file.

From the user side no special improvements are noticeable, games still show only splash screens at best :-)

There may be various bugs in the interface after refactoring, they will be fixed over time.


The release with unlucky number 13 was split into two releases: 0.130 and 0.131. These superstitious programmers..

  • MMU support

  • Support cache emulation

  • Dynamic recompiler (JITC)

  • Improved emulation of graphics FIFO

  • Many other minor improvements

All these things were added experimentally and at the moment the cache and recompiler are temporarily disabled. If you are a developer, you can rebuild Dolwin with the cache and recompiler turned on.

The cache is enabled with the command CacheDebugDisable 0.

The recompiler is turned on in SRC\Core\Gekko.cpp, line 20 (but the interpreter must be disabled).

Between 0.130 and 0.131, I will try to fix all incomprehensible bugs with cache and recompiler so that they are included in the next release.
