Dolphin Progress Report: August 2021

Many gaming communities over the years have reached out to thank emulator developers for their efforts. Emulators are an important part of many classic game communities and give players access to features like netplay multiplayer, modding, and savestates, while also opening up the doors to enhancements not possible on console. Sometimes it's simply more convenient to use an emulator that runs on your desktop, tablet, or phone rather than to dig out and hook up the original console every time you want to play one of your favorite games. However, it's important to state that our relationship with gaming communities is mutual, and without the help of players and fans, there's no way we could handle maintaining a library of thousands of games.

In this Progress Report, the gaming communities were the direct catalyst to many of the changes. They went on difficult debugging adventures, caught small issues that would be invisible to anyone who wasn't extremely familiar with the game, and even came up with patches to make games friendlier to emulator enhancements. All of these contributions, even if it's not code, are appreciated and help make Dolphin what it is today.

So, without further delay, let's get started with the August Progress Report! Enjoy.

mGBA Integration: Introducing the Integrated GBA

Your eyes are not deceiving you. As of 5.0-14690, Dolphin now has mGBA directly built into it as a new way to handle Game Boy Advance connectivity with GameCube titles. For those who don't know, mGBA is the most renowned and accurate GBA emulator of this era and has been rapidly improving since its inception. Recently, we wrote about mGBA adding support for our TCP GBA protocol, but this is something completely new. With integration and synchronization work done by bonta, connecting your favorite GameCube titles with a Game Boy Advance for multiplayer and other bonus features is now greatly simplified. Dubbed the Integrated GBA, a stripped-down version of mGBA will boot up alongside Dolphin when set to one or more controller ports. These mGBA instances are clock-synced to GameCube emulation for impeccable connection stability. By bringing these two emulators together in one package, GBA connectivity features now work with popular features like savestates, input recordings, and netplay! All of this comes with the added bonus of improved performance and compatibility. If you don't believe us, check it out yourself!

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.

mGBA and Dolphin Connectivity

Connecting multiple emulators together is a complicated and difficult task. This task becomes even more difficult when you consider connecting two different emulators together. You have to understand two different consoles, how these systems communicate with each other, adapt to latency restrictions, and have expertise across two different projects. In the case of GameCube to Game Boy Advance connectivity, we are incredibly lucky to have had talented developers from both GBA and GameCube circles create our current protocol for supporting "GBA" controllers. Dolphin's GBA connectivity has stagnated for some time with …

Dolphin Progress Report: October and November 2020

The past two months have been quite busy with a lot of features and fixes spread out between a lot of contributors, new and old. It's only fitting then that we've seen some important fixes for ancient bugs and new ideas bringing in new features. Even if the game you've been playing is already running fine, developers are hard at work coming up with ways to make things even better. Take for instance a new infrastructure that allows Custom Texture Packs to customize what controls show up in games depending on how you've configured your controller in realtime! Also, getting that perfect angle is a bit easier with the new "virtual notches" system, perfect for difficult platforming challenges in games like Super Mario Sunshine!

There's something missing in this picture... or is there?!

Enough teasing, we've made you wait long enough. It's time for the October and November Progress Report!

Dolphin Progress Report: April 2020

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!

Dolphin Progress Report: November 2019

One of the most enjoyable parts about being a part of emulation is seeing the classic gaming community use the tools we provide to find hidden bits of joy that would be impossible to reach otherwise. Freelook has found secret after secret hidden away just off-screen, and there's even a youtube series that focuses entirely on them! Savestates basically made speedrunning and TASing possible, allowing for quick testing of routes and sequence breaks to push games to their limits. But communities can go far beyond that, with tools now allowing us to look directly into game files and expose unreleased and rare relics. In the past couple of months, we've had two incredibly interesting leaks: A TGC file ripped from a store preview disc containing a pre-release version of The Legend of Zelda: The Wind Waker and a very early prototype of the never released Spider-Man 4.

Released versions of the game show this intro screen during the day, but this pre-release version is at night!
We can't say for sure that the Spider-Man 3 film doomed the Spider-Man 4 game, but, well, it probably did.

Each of these games give a very specific look into their development. Wind Waker's prerelease demo is very close to the retail product and fully playable beginning to end without the imposed timer. Those that have looked into it have found a plethora of minor differences and glitches between this build and the one Japan would see a few weeks later. Spider-Man 4 on the other hand, never saw release and this was just about everyone's first look at the game. While it emulates just fine in the latest development builds, it does not run in Dolphin 5.0, due to broken support for unencrypted Wii discs. If you do run it, you get to see an incredibly early preview of the game with many non-existent textures, placeholder graphics, and incomplete collision detection. Still, we're happy that Dolphin was chosen as a platform to test out this unique prototype and the game worked without needing modification. With that bit of interesting news out of the way, let's get back to our regularly scheduled Progress Report.

Dolphin Progress Report: August and September 2019

Earlier this month, an interesting development within the Wii reverse engineering scene was announced as Fullmetal5 revealed that they had hacked the Wii Mini via a Bluetooth exploit. This bookends a flurry of a Wii Mini hacking, including rigorous hardware modding by DeadlyFoez. You may be wondering, "Wait, wasn't the Wii hacked over a decade ago?". That's true, but the Wii Mini stubbornly remained unhacked all the way into 2019.

This resiliency came from the Wii Mini's cut down nature: it physically lacks the attack vectors that were used against the original Wii. In total, the Wii Mini was missing GameCube support, with no GameCube controller ports or Memory Card slots, lacked internet and browser support, and they completely removed the SD card slot. With so few attack surfaces, hackers have had to get inventive. DeadlyFoez created "FrankenWiis", mixing Wii Mini hardware and standard Wii hardware, to create exploit options and dump the Wii Mini firmware. This was as far as anyone could go, until Fullmetal5 found the holy grail: an exploit in the standard Wii Mini configuration, through the Bluetooth stack! This exploit completely opens the Wii Mini, allowing for arbitrary code execution to dump and/or load data over the Wii Mini's USB ports. The exploit is currently not public, but when it is released, users will be able to run homebrew on the Wii Mini just like any other Wii console, without any hardware mods. If you're interested at all in the Wii Mini and its many differences, feel free to checkout some of DeadlyFoez's videos of their efforts. It's a very strange little machine.

Update: During the writing of this article, the exploit was released!.

With the Wii Mini Menu dumped, the main question for us was... does it run in Dolphin?

The Wii Mini Wii Menu running in Dolphin!
Here is a normal Wii Menu for comparison. The Wii Mini lacks the Wii Shop, all internet channels, and the SD Card.

The answer is yes! In addition to that, Fullmetal5 also adjusted Dolphin to correctly detect Mini Wii Menu versions. While there isn't much practical use for running this cut down Wii Menu in Dolphin, it was exciting to finally see one of the last unhacked pieces of Wii hardware fall. We'd like to wholeheartedly thank everyone involved for their efforts toward Wii hacking and preservation.

With that out of the way, we have a few changes of our own to go through. While the end of the summer was a bit slow, there are still some essential fixes for several popular games and finally EFB Access is working correctly on Adreno devices... at least in Vulkan. Let's jump into August and September's Notable Changes without further delay!

Dolphin Progress Report: June and July 2019

As seems to be happening annually, due to a short summer lull, we decided to combine the June and July Progress Reports. As you may have noticed, we're a few days into August at this point and things ended up running a bit late. That's actually a consequence of how we do these Progress Reports - we sometimes will go through big changes, test them, and get developer input on how they work in order to better explain them. In late July, a mixture of late changes, unexpected behaviors, and an extremely subtle game bug forced us to delay things while we sorted everything out. In this case, the end result didn't actually affect Dolphin, but does make for a better read as everything finally came full circle.

While we apologize for things being late, we do have a rather wide variety of changes that hit over the last two months to make this Progress Report extremely well-rounded. Whether you're looking for GUI updates, Android, fixes to ancient bugs, and even one feature inspired by a developer who saw Dolphin being used during Summer Game's Done Quick!

Dolphin Progress Report: May 2019

The past few months have been quite hectic with a slew of gigantic changes requiring lengthy articles alongside them. These big features all hitting together seems to have brought up a talking point in the community would be irresponsible to ignore. Everyone wants to know when Dolphin 6.0 is coming. After all, Dolphin 5.0 launched nearly three years ago and lacks features like Ubershaders, Bluetooth Passthrough, Hybrid XFB, Emulated Motion Plus... the list goes on. Unfortunately, we have to announce that we aren't especially close to a release right now.

A release build is about more than just having exciting features, it's meant to be stable, reliable, and highly compatible. Since Dolphin 5.0, there have been a lot of minor and major regressions that haven't been fully worked out yet. Whether it's a game like Ed, Edd, & Eddy: The Mis-Edventures hanging on a loading screen or audio being broken in Resident Evil 2. There are dozens, if not over a hundred of these little issues that just take time and effort to address. Some of these issues are close to being resolved while others haven't even been investigated yet.

All we can ask of users is to continue using the latest development builds, continue reporting bugs, and be patient with the next release. With that out of the way, it's time to get to this May's Notable Changes. As always, users who want to try these features can download the latest development builds on the download page or use the auto-updater to get a new dev build every month automatically. Enjoy.
