Dolphin Progress Report: September 2015


After some minor delays, Dolphin's new issue tracker is up and running, with all of the old issues preserved and imported. It hasn't taken long for things to heat up on our new tracker despite trying to keep it on the down low while it was being tweaked. A mixture of delays with the issue tracker and new bugs in our stable branch cropping up has pushed back …

Dolphin Progress Report: August 2015


If you count the number of notable changes throughout August, you may think it was a down month. Aside from a flurry of Dolphin ARM updates, there really wasn't much to choose from. A lot of the major projects remaining on the emulator are multi-month affairs, so contributors seemingly disappear from the progress reports for months only to return with a bang. Then there's Sonicadvance1, who keeps trucking on with Dolphin ARM on an almost daily basis. Despite the miniscule number of big additions, the big …

The New Era of HLE Audio


In early 2013, Dolphin had began its first steps in a new focus on accurate emulation. The 3.5 release represented a shift in the emulator's focus, and as such, saw great improvements in terms of compatibility and accuracy over the previous release. But one area that stuck out like a sore thumb during this era was the quality of High Level Emulation (HLE) audio. Hundreds of games suffered from crashes associated to audio, and thousands had significant problems, with missing effects, incorrect volume, and random bursts of …

Dolphin Progress Report: May 2015


After a slow April month, a chaotic May more than makes up for it. On top of working on an emulator, developers had their hands full with relicensing. It's always a good month when you can look back at the issues that were fixed and go "phew," hoping to never, ever encounter anything like that ever again.

A wide variety of issues, features and enhancements saw important updates this month that increase playability and make the emulator more robust. Please enjoy this month's progress report!

Dolphin Progress Report: April 2015


On the one year anniversary of the Dolphin Progress Report, we have a fairly slow month in terms of emulation development. While there are certainly some big things on the horizon, unfortunately development managed to hit one of the gaps where there were mostly some fix-ups and optimizations this month with only a few changes that users will notice.

With that, let's take a look at this month's notable changes.


Notable Changes

4.0-5948 - On Old Savestates, …

Dolphin Progress Report: March 2015

Console add-ons and linking emulation are almost always difficult tasks. Worse yet, availability, software support, cost, and even popularity can limit the ability to get these hardware add-ons documented and emulated. While their are numerous examples spanning tons of consoles and their respective emulators, this month, we're talking about GameCube to Game Boy Advance Connectivity.

Timings and synchronization are a given on real hardware; games know how it's going to work and many expect it to always work perfectly. When it doesn't? Certain games break. Now imagine a …

Dolphin Progress Report: October 2014

Progressreportheader-October2014.jpg


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 …

Dolphin Progress Report: September 2014

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 …

Dolphin Progress Report: August 2014

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 …

Dolphin Progress Report: July 2014

Progressreportheader-July2014


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 …
