Dolphin Progress Report: February, March, and April 2022

After a long wait, the Progress Report is back! This time it wasn't so much from a lack of content, but from a lack of content creators. The past three months had illnesses hit one of our writers and the other had a very challenging move. Even with these major hurdles jumped, we're not even close to 100% yet. It's been a battle to get caught up with all of the big changes to Dolphin the past couple of months and because of that this report is a tad late.

Needless to say, there's only one way to start catching up, and that's to get to digging through the past three months of Notable Changes. Enjoy!

Dolphin Progress Report: November and December 2021, January 2022

This year, we've hit an important milestone that's been in the works for nearly a decade. In late 2012, Sonicadvance1 began work on Dolphin's ARM JIT. Back then, there weren't any devices that had even a sliver of hope of running Dolphin close to full speed, but that wasn't really the goal. All he wanted to do was see if it could be done; it sounded like a fun, challenging project. However, as time passed the idea turned into more than just a passing curiosity. Users were more than happy to donate to cover the hardware cost of staying on the bleeding edge of a rapidly evolving ecosystem, allowing ARM development to flourish. By 2015, Sonicadvance1 astounded developers and the community alike with footage of Mario Kart: Double Dash!!'s time trial mode running close to full speed.

We've come a long way.

On that note, we're happy to announce that Dolphin's AArch64 JIT has finally reached feature parity with Dolphin's x86-64 JIT. This means that every PowerPC instruction that the x86-64 JIT supports along with every major JIT feature are now supported in the AArch64 JIT! And this is a great time for ARM in general, with each generation of processor pushing the boundaries and companies like Apple adopting the architecture for larger and higher power devices like their M1 Mac line. For those on mobile phones and tablets, Adreno powered devices provide decent enough graphics drivers to get a reasonable experience at this point. And with a critical bottleneck getting fixed just days ago, performance on Adreno GPUs has skyrocketed. You won't have to scroll far for that news, we promise.

But that's only the tip of the iceberg; we've had three months worth of changes pile up and some other important infrastructure news. We've improved the user experience on macOS significantly and restored support for older devices. In fact, enough has happened that we'll be detailing the status of Dolphin's macOS support near the end of the report.

And... we haven't even talked about any emulation fixes yet. The past three months have had tons of changes that would have normally been the highlight of a Progress Report. The three month gap between reports was not because of a lack of changes. Want to take Riivolution games on netplay? You can. Hate the EA VP6 bugs? Make them a thing of the past with a new option. Wish your favorite LogicOp game worked on GLES or MoltenVK? Odds are, it does now! The list goes on, but outlining everything would take way too long, so let's just dive in. Please enjoy the November, December, and January Progress Report!

Dolphin MEGA Progress Report: April and May 2021

After finishing up the macOS M1 article the blog staff took a little break. Then they saw the date.

Oh shi-

Upon looking at the actual changelog, however, something became readily apparent: this wasn't going to be just a Progress Report; this was going to be a MEGA Progress Report. The long rumored time era of developers merging everything at once had finally come to pass. We have graphical fixes for Super Mario Galaxy and Luigi's Mansion, crash fixes for Star Wars: Rogue Squadron III, Xenoblade Chronicles, Ultimate Spider-Man, The Legend of Zelda: Skyward Sword (AArch64), and new features that make playing games more pleasant! And about AArch64, there are a litany of optimizations and fixes that will change things across most of the library.

And we could go on: Bounding Box, Interpreter, GBA to GCN connectivity, GPU Syncing, Mouse Locking, and still more! There's even a lengthy dev diary at the end for good measure explaining how the great mystery of Pokemon Box's was finally solved. The only way to do it justice is to do it right. So buckle up and get ready for the April and May MEGA Progress Report.

Dolphin Progress Report: September and October 2018

Since the Dolphin 5.0 release, Dolphin has had opt-in usage statistics reporting to help us determine what hardware and builds users are using. Recently, this feature was also added to Dolphin Android, letting us see that around 10% of our users on development builds are using the Android version of Dolphin. Obviously, Dolphin on Android isn't going to be a perfect experience for quite some time, but in the meantime we will continue to add features and try to make the Android experience as clean as possible, even if the hardware is going to struggle with emulating GameCube and Wii games.

As a part of that, a lot of the major GUI features from the desktop version of Dolphin have been ported over. Just this year, we've seen important features like INI support, INI configuration, auto-update support, and even statistics reporting. Unfortunately, trying to bring the desktop experience to phones has caused some confusion that would seem like second nature to desktop users. Savestates in Dolphin are not compatible between builds and a lot of phone users that had been solely relying on savestates were in for a rude awakening during the next auto-update.

An unfortunate series of events lead to some deserved negative reviews on the Appstore and other mediums. With the brand-new auto-update feature came a bunch of broken savestates for users with no warning whatsoever. Unlike the desktop builds, savestates are immediately available directly from the context menu during emulation without any warnings or other information. Regardless of auto-update, relying solely on savestates for your progress is a risky proposition and we highly recommend using in-game saves as a more permanent way to save your game.


"Updated without warning and my save states were completely lost. The game's save function broke, so those were the only saves I had. For a GameCube emulator on Android it was working really well, but losing all my progress because they couldn't make old save states work with the update was really disappointing." -- User review on the Dolphin App within the Google Play Store


Dolphin's design doesn't really allow for savestates to work between different builds safely, so we were left with a difficult decision. Users randomly losing their save data is not acceptable, but removing savestates on Android would be awful. So as a compromise, we've added an option to enable savestates in the configuration menu, with an explanation of how they are intended to be used so users can understand the risks. We're sorry to anyone who ran into issues in the meantime, but as Dolphin on Android becomes a more legitimate option in the future, we're likely to run into more of these growing pains. All we can do is ask users to be patient and continue to report issues as we go forward.

Now that we've got that out of the way, there's plenty of other notable changes to get through this month so let's start chewing through them!

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, …

Dolphin Progress Report: April and May 2018

Users of Dolphin may have noticed that things look a little bit different in the GUI. That's right, mid-April DolphinQt was unleashed to the masses as the default GUI! It hasn't been without some expected headaches and growing pains, but, overall most of the features are working and the transition is going along as smoothly as we could have hoped. For those having problems, the DolphinWx.exe is still included and will be updated with all the core changes.

Considering that we spent a whole monthly article on Qt, let's get into some actual emulator changes. In between the mountain of Qt changes has been an explosion of progress and fixes hitting everything from CPU edge-cases to Vertex Loader fixes! With that, please enjoy this month's notable changes!

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 …

Dolphin Progress Report: June 2017


June was a month where a lot of important features were merged, but few of them had to do with actual emulation. Every emulator has its own philosophy and goals. While the primary goal is usually to emulate the console at hand, many emulators place secondary goals on various features and ideas. One of Dolphin's secondary goals is to make using the emulator as simple of a process as possible. There are lots of features that try to simplify things, like the Game INI system, support for real …

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 stood out - slowdown affected audio for the first time for a majority of users. This was seen as an unfixable issue. After all, it doesn't make sense for audio to run full speed if nothing else is! The issues were closed and the concern was filed away until users got used to the change.

Long-term, we did learn something from this dilemma. While synchronous audio was undoubtedly better for the project and solved the major emulation issues with audio, it caused a whole bunch of presentation issues we neglected to fix... until now.

This month, we have a lot to offer. Custom texture support gets supercharged, the JIT sees some important maintainability changes, and a smattering of audio changes include a huge presentation change to audio that will help users hear games pleasantly even under slowdown.

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 the new recruits are the final Virtual Console game, a massive Wii MMO that installs itself to USB, two games where we're almost certain the developers purposefully put code in to defeat Dolphin, and two channels developed by the remnants of Factor 5.



This is a massive Progress Report, so buckle up and enjoy this month's Notable Changes.
