The Dolphin Progress Report is not only about featuring high impact changes, but also smaller changes that do interesting things, changes with interesting stories behind them and more. This month has a ton of everything to offer. Dolphin is graced with a new graphical enhancement that will have games popping right out of the screen, a new way to accurately use native controllers, more MMU optimizations, graphics fixes, and even a few other surprises sprinkled in. Some of these changes made us regret running the Best Of blog …

A single merger can represent days, months, or even years of work. Most of the commits are relatively small, but once in a while you get absolutely huge changes like Tev_Fixes_New or the GLSL rewrite that span across years between initial concept and merged code. There's a special sense of accomplishment when one of the long awaited changes finally show up in the emulator. The number of commits and the amount of code changed; neither of those indicators often tell of the trials faced by the contributor over …

Optimizations seem to beget even more optimizations. It was big news when last month we got a nifty 26% boost in CPU performance, but somehow, two dedicated devs managed to top it this month. Not to be upstaged by Fiora , comex has dropped new features and two absolutely gigantic performance commits. By making tricky use of registers and native RET behavior, two of his merges alone result in a massive 16% performance boost to games.
Not to be outdone, Fiora has continued her rash …

This month, the story can't be anything else but CPU optimizations and fixes, after Fiora decided that if the code is in the JIT, she will make it faster. Nothing is safe from her. Since the end of July, Dolphin's JIT CPU core has seen a 26% performance boost in the Dolphin Benchmark. That is not a typo.
On the accuracy front, we've got some nifty changes that fix bugs going back to the beginning of time for Dolphin. Some ancient audio bugs bite the dust, some …

In programming users usually don't see or care about what's going on on the inside all that much. All those boring code optimizations may make things easier for the developers and slowly improve the emulator, but hard-to-quantify changes are not exactly exciting. This month was full of those, with several hundred changes yet very little the general user would find interesting. Nevertheless, in the sea of code improvement, there are some real treasures: big performance improvements, some ancient bugs squashed, regression fixes, and some exciting new features to …

When an open source project is really working, things can move frighteningly fast. One developer can focus on a feature while others are reviewing the code and preparing it for merge, allowing things to move forward in a very streamlined fashion. This not only gets things done faster, but each coder can specialize in what they do best, producing the best possible product for the user base.
When things come together just right, months like this can happen. The June Progress Report is a massive monument to months …

The single greatest mission of an emulator is the preservation of a console and its games. The Dolphin team has made a commitment to that, especially over the past two years. After nearly a decade of guesswork, hacks, and "good enough" emulation, the developers took a stand to strive for something greater. This change in goals has forced difficult decisions had to be made again and again.
This past month has been one filled with the benefits of working with an accuracy oriented mindset. Not only …

The development cycle for Dolphin is a fairly weird and largely inconsistent process to those peering in from the outside. There are gigantic leaps with huge merges such as the tev_fixes_new merge we recently reported on, but those tend to be the exception. While it is great to have big articles on huge changes, those smaller changes are just as important for the emulator, often adding features and improving the user experience. The Dolphin Progress Report is a monthly update highlighting some of the improvements that keep the …

The GameCube GPU is a complex, tight-knit piece of hardware with impressive features for its time. It is so powerful and so flexible, it was used unmodified within the Wii architecture. For a comparison, just imagine a SNES running with an NES's graphics system. This is completely unheard of, before or since. The GameCube is a remarkable achievement of hardware engineering! With its impressive capabilities, emulating the GameCube's GPU has been one of the most challenging tasks Dolphin has ever faced.
As well as …

The Legend of Zelda: The Wind Waker is one of the most popular Gamecube games, if not Nintendo games, in existence. Its mixture of an open world, sharp dungeons, and an inventive art style turned heads more than ten years ago when it was released. Dolphin has had its share of problems with Wind Waker, but none could be so frustrating as its mishandling of the heat distortion.
The Issues
This issue actually crops up in two ways throughout Wind Waker. The more common way is that all of the flame …
