Dolphin Progress Report: February and March and April 2019

The last few months have been absolutely hectic, with several long-awaited features hitting the emulator all at once. In order to keep users up to date with these major changes, the blog staff has been busy with feature article after feature article. It has been exciting, but also pretty exhausting! With us burning the candle at both ends to keep up with development, the Progress Reports have fallen a bit behind.

So here were are, bleary eyed and with three …

The New Era of Video Backends: The Unification of VideoCommon

It's not common for a rewrite to be something that warrants an article, but, this is one of the exceptions. Over the past few years, parts of Dolphin's video core have seen renovations to make way for new features, but a fundamental problem remained. Dolphin's video backends suffered from both having too many unique features while also duplicating tons of code from the other backends, making it difficult to add new features and maintain old ones.

Those that have followed Dolphin from the very beginning may remember that its video backends …

The Current State of Dolphin on Android

Dolphin on Android has had a bit of a checkered history since its inception. Users loved the idea of being able to take their favorite GameCube and Wii games on the go, but expectations and reality have never quite aligned. When Dolphin was first uploaded to the Play Store, developers tried to make it absolutely clear games wouldn't be playable, even going as far as calling it "Dolphin Emulator Alpha". Unfortunately, despite many warnings, many people got their hopes up the moment they saw Dolphin was on the appstore and …

Dolphin Progress Report: July 2018

On July 13th, 2008, Dolphin went open source, now just over ten years ago. While it could be easy to drift off into how much things have changed... there's one particular feature that has never quite lived up to the hype despite debuting that very same year - netplay.

As surprising as it may sound Dolphin Netplay has been around since the emulator went open source. For roughly a decade, users have tried their hand at taming the beast of synchronizing multiple instances of a GameCube and Wii despite their …

Myth Debugging: Is the Wii More Demanding to Emulate than the GameCube?

On the Dolphin Forums, one of the more common questions that come up is "How come I can emulate this Wii game just fine but this GameCube game is slow?" While those more knowledgeable about the intricacies of emulation may roll their eyes, it does warrant some explanation. Usually when stepping down from a newer console emulator to an older console emulator, the minimum requirements for emulation drop significantly. While there are some exceptions when dealing with exceptionally obtuse hardware, that concern doesn't hold up here: The GameCube and Wii, …

To the Screen with Hybrid XFB

Dolphin has been around for over 14 long years at this point. Goals, expectations and standards have shifted quite a bit since the beginning. At one point, just booting a game at all was good enough, regardless of what you would see or hear! Compatibility has gone from a few select titles to almost every game released across two consoles. Considering all of that, it should be no surprise that some solutions that worked in the past slowly came to be a burden going forward. In this case, we're talking about …

Ubershaders: A Ridiculous Solution to an Impossible Problem


When you're playing your favorite game on Dolphin with a powerful computer, things should run fairly well. The game is running full speed, there are no graphical glitches, and you can use your favorite controller if you want. Yet, every time you go to a new area, or load a new effect, there's a very slight but noticeable "stutter." You turn off the framelimiter to check and your computer can run the game at well over full speed. What's going on?

The slowdown when loading new areas, effects, …

Dolphin Progress Report: April 2017


One of the more difficult parts of being an emulator is balancing accuracy, performance and presentation. When Dolphin replaced the hacky, broken asynchronous audio with the synchronous New AX-HLE and New Zelda-HLE implementations, audio accuracy greatly increased! It came as quite the shock when users started complaining about this change and demanding asynchronous audio's return. Some of the criticisms were valid; there were bugs in early synchronous audio causing increased latency that weren't present in asynchronous audio.

All of these growing pains were eventually fixed, but, one complaint …

Dolphin Progress Report: January 2017


Sometimes, it's easy to forget how much work there is left to do on a refined emulator. While the rush of getting a new game to boot or discovering a crazy feature hidden within an obscure gem never gets old, those moments do tend to get further and further apart as accuracy increases. As if to defy fate itself, excitement reigned over the month of January as a plethora of ancient bugs were fixed and many unbootable titles finally saw their day of reckoning come to be!

Among …
