Dolphin 4.0 released, includes BETA support for Wii official online multiplayer and more

Dolphin Emulator has just gotten a new update in the form of Dolphin 4.0; major new additions include support for official Wii online multiplayer, global user directory, alpha support for ARM/Android and new UI among the other important updates.

If you aren’t up to date with the Emu scene then you’ll be glad to know about Dolphin. Dolphin is a very popular Wii and Gamecube, second to only PCSX2 in my opinion. Dolphin is currently able to play many of your favorite Nintendo classics in Full 1080p and even 3D which weren’t possible on the original consoles.

I’ve been using Dolphin Emulator for a few years now and it’s been quite a journey. In the start as you would expect you would be lucky to get a game running at 20fps, but the recent updates have most games running at full speeds on a decently equipped rig.

Dolphin 4.0 is one of the biggest updates to hit the emulator and I really hope these updates continue in the future.


Below is the full changelog from the official Dolphin site:

Beta support for the Wii official online multiplayer (Documentation)

This is a feature that has been coming for a long time. More than two years ago, Matthew Parlane and Shawn Hoffman started working on emulating the Wii Wi-Fi networking API in order to run Wii online multiplayer games inside Dolphin. While it was not an easy change in itself, it also required a lot of modifications to core components of the emulator to be implemented properly (for example asynchronous IPC HLE) and a lot of debugging. It is now working well enough that we are releasing it to the public as a beta: don’t expect everything to work, but popular games like Mario Kart Wii or Super Smash Bros Brawl can be played online right now.

Alpha support for ARM/Android

About two years ago, Ryan Houdek began the implementation of an ARM port of Dolphin, designed to run on powerful mobile phones and other ARM devices in the future. After a long time spent making Dolphin work well on both ARM and x86, Dolphin can now emulate GameCube and Wii games on recent Android phones. This support is still in early alpha stages: crashes happen, it’s slow on Qualcomm hardware because of graphics drivers issues, and it is still missing a ton of features. Nowadays, Dolphin on Android is a two man project: Mathew Maidment is helping Ryan with the UI and making the Android version actually usable.

Global User directory on Windows (Documentation)

This is not exactly a major feature, but it is a big change in how Dolphin works on Windows, and requires user interaction to move from the old configuration system to the new one. Before 4.0, Dolphin configuration was stored next to Dolphin.exe, often causing issues when upgrading to a new version of Dolphin. New versions of Dolphin use a centralized location to store the configuration for all builds, usually My Documents\Dolphin Emulator. The documentation article linked above explains the details of this move, as well as what you need to do to migrate your old configuration to the new system (if you were using Dolphin before).

New AX DSP HLE emulation code

DSP HLE is the main audio emulation technique used in Dolphin. Before 4.0, it was extremely inaccurate and full of bugs, mostly due to how it was implemented. Dolphin 4.0 introduces a full rewrite of the audio emulation used in 99% of games, fixing hundreds of audio related bugs in Dolphin. On the flip side, it is now required to run a game at full speed to get full speed audio out of it, which is a direct consequence of fixing these bugs.

A lot of more minor changes were also integrated in that new Dolphin release:

New look

A new look has been designed by MaJoR for Dolphin (new icon, new icon theme) and implemented on a new version of the Dolphin website by Pierre Bourdon.

Wii Balance Board and GC Steering Wheel support

Support for these two devices was added respectively by Matthew Parlane and skidau. The Wii Balance Board is not emulated and requires the real device to be used.

Wii Remote support improvements

Wii Remote background scanning was implemented to more closely match how a real Wii detects remotes, and support for -TR (Wii Motion Plus Inside) remotes was implemented for Mac OS X. A new documentation guide about Wii Remotes on Dolphin was also written by MaJoR to help Windows users with Wiimote issues.

Fastmem support for Linux and OSX

Fastmem is an optimization for Dolphin’s CPU emulation, which was previously only implemented on Windows. Adding Fastmem support on Linux and OSX boosted the performance by 15 to 20% on these platforms.

New OpenAL audio backend

This audio backend, written by skidau, supports three important features that are not implemented in other backends yet: configurable audio latency, surround sound using the information contained in the Dolby Pro Logic II encoding used by most GameCube and Wii games, and support for sound stretching to make audio slow down when a game does not run at full speed.

OpenGL video backend rewrite

The Dolphin OpenGL video backend was rewritten by Markus Wick in order to use newer features of OpenGL and be GLES3 compatible. As a result, the OpenGL backend is now the fastest Dolphin video backend on NVIDIA cards.

NetPlay stability and usability improvements

Before Dolphin 4.0, GameCube NetPlay was at best a curiosity. 4.0 added a lot of NetPlay related changes which makes it actually usable for most games, but sometimes with performance issues. Super Smash Bros Melee players are now using Dolphin for regular online NetPlay tournaments, and it just works. Read the official NetPlay guide for more information.

Mac OS X support enhancements

This release also adds a few small OS X improvements: the Dolphin DMG bundles are now signed by a valid developer ID and do not require you to disable Gatekeeper to be used. The emulator is also Retina Display aware and handles the logical scaling better on these screens.

Icon themes support

In addition to shipping with a new default icon theme, Dolphin now allows you to make your own themes and share them with other people.

There are plenty of new additions especially the BETA for Wii online multiplayer.  The new UI also looks sleek and the improves to plugins further improve the compatibility and stability of the emulator.

Dolphin is also available on Android and while it still isn’t in playable form, it does work as a proof-of-concept on Android platforms. This new update also adds Alpha support for ARM/Android which manages to run Dolphin on recently released android phones. Even if the gameplay is still slow and there are frequent crashes, this is a good step in the right direction. Currently, it is a two man team only that is working on making it playable on Android. Hopefully, they can run some of the more popular Wii/Gamecube games with further updates, which would be amazing.
