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!
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.
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!
It's the beginning of the month and time for another Dolphin Progress Report! ...That line doesn't exactly work when it's midway through the month, huh? This Progress Report ended up being a very technically challenging report to write with several huge rabbit holes that go through the history of Dolphin and the games themselves. The first rabbit hole showcases TMEM, the GameCube and Wii's texture cache. Dolphin's approach to emulating this bit of the hardware has been to effectively ignore it exists. Trying to even begin to rectify the problems with this approach and explain the reasoning behind why it sort of wasn't emulated go very, very deep. This Progress Report also contains collaboration with the PCSX2 development team as they helped us understand some of the behaviors of Floating Point Math on the PlayStation 2. The fact that the PlayStation 2's floating point behaviors mattered to us for this Progress Report should tell you the kinds of things we were up against when writing up the changes.
If that wasn't enough, Dolphin also welcomed support for a wealth of mods through support for Riivolution. An easy to use GUI for launching Riivolution mods was added both to desktop Dolphin builds and Android. Speaking of Android, users may have noticed we pushed out an early beta last month. This beta was mostly to showcase and let users on the Play Store try out the newly finished Cheat GUI! We'll finally showcase that after a lengthy delay between when that extra beta was pushed and this Progress Report. While it's not related to Dolphin directly, Apple released the new M1 Max and we got our hands on one to see how it stacks up against the M1 with some rather interesting performance numbers at the end of the report.
With that out of the way, there's no point in delaying things any further. Please enjoy these rather lengthy Notable Changes!

Emulation is often seen as this suspect gray area of gaming that is tolerated but always on the edge. There's a lot of negativity and questions around the merit and purpose of emulation. In contrast to that narrative, the overwhelmingly positive reaction to some of the features added the last few months, including heartfelt reactions from users, make all of the challenges and struggles so much easier.
As we drift further from the heyday of the GameCube and Wii, we've been seeing a greater impact not only on the past generations of gamers, but the current one. It was heartwarming to see long-time users able to play Four Swords Adventures with their kids or friends across the world. The gratitude we received from users finally able to try previously hard-to-access features in their favorite games was so appreciated. We love these games and consoles the same as you, and we want to make sure that they live on.
Sometimes with all the negativity in emulation, it's refreshing to have something that makes both the developers and the users happy. And while we'd love to revel in past accomplishments, there's still so much more work to be done. We graciously thank everyone for their kind words over the past few months, and hope you continue to enjoy using Dolphin Emulator. With that said, it is about time that we get started with the June and July Progress Report.
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.
Sometimes the introductions to the Progress Reports are the hardest part to write. The Dolphin Blog has been running for many years, and we've gone through hundreds of changes that affect thousands of titles. We've gone into detail on all kinds of games, from top sellers on the consoles to obscure titles that most of us wouldn't have known existed if not for some random bug report. Despite all of these exciting changes, despite seemingly seeing it all over the years, we still see things that amaze us. The GameCube and Wii library still have a few tricks up their sleeves and developers continue to come up with crazy new optimizations and features that keep pushing Dolphin forward.
It's hard to express how happy we are to not only be writing these articles, but still have interesting things to write about. In fact, we were working on a feature article spotlighting some new features, but things were unfortunately delayed. As such, this month's Progress Report is a little hurried. What exactly got delayed? Well, we'll have more on that later this month. For now... please enjoy this slightly belated Dolphin Progress Report!
Welcome to the Dolphin Progress Report for December 2020 and January 2021! Things ended up running a little behind for this report due to some technical details that we needed to hammer out for a few of these entries. We on the blog team are familiar with the emulator, however there are a lot of technical details that are simply beyond our expertise. Going from things like the AArch64 JIT to GUI changes to IOS updates to game patches that go into low-level hardware behavior is enough to make anyone's head spin! More often than not, we rely on core developers and the authors of a specific change to help us understand what a pull request does so that we can express its purpose accurately here on the blog.
With Progress Reports coming at a mostly bimonthly schedule at this point, this means that sometimes authors have moved onto different things or aren't available to talk. As a blog about emulation, getting these details correct about the various changes and how the emulator works is one of our highest priorities. So, with that out of the way, we hope you enjoy this belated Dolphin Progress Report!
Kept you waiting, huh? This summer we had our longest break since we started writing these Progress Reports. Some other obligations came up and a bit of a lull in development gave us the opportunity to postpone things for an extra month. As it turned out, pushing things back might have been a bad idea, as the floodgates opened and now there's a gigantic backlog spanning three months to get through! To put things into perspective, since our last Progress Report, the last Nintendo Wii games were released, Dolphin Android had a huge user experience overhaul, and Nintendo's very own GameCube and Wii emulator hit the Switch with Super Mario 3D All Stars.
So without further delay, let's start getting through the backlog. This one is a bit of a doozy.
We've got a lot to get through the past two months. Headlining it all is that we're happy to announce support for a new compressed disc format developed specifically for Dolphin: RVZ. This lossless format allows for near top of the line game compression without compromising the integrity of ISOs, while also maintaining performance and stability. But what good is compression if emulation isn't up to snuff? The past two months have been chock-full of emulation and usability fixes for both Android and Desktop Dolphin! There's a little bit of everything, from graphics emulation fixes, memory card and savestate compatibility changes, to obscure features like being able to report thermal data to games and homebrew!
Rather than delaying any longer, let's just dive in now! Please please enjoy the May and June Dolphin Progress Report!
It feels like it's been some time since we've had actually had a monthly Progress Report. This is because there haven't been as many major changes landing, making it harder to fill out a substantial article. That isn't to say that things have slowed down, these smaller changes increase the quality of life for users and add up, especially when jumping from older builds to the latest. However, these changes are a lot harder to show and feature in a Progress Report compared to things that actually affect the core emulation and games. This time around, we had more than enough on our plate to write about, including support in the latest builds for a very interesting game: The Metroid Prime 3's E3 2006 Beta.
But before we get to the new changes, we need to cover something we missed last month. So, without further delay, please enjoy the mostly April Progress Report!
