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.

Temptation of the Apple: Dolphin on macOS M1

From the announcement made on November 10th, 2020, users have had high hopes for the new Apple M1 devices. With its powerful Apple Silicon processor smashing benchmarks all over the place, users and developers were both asking if a native Dolphin build would be possible. Now we have the answer.

Apple's M1 hardware is incredibly powerful and excels at running Dolphin. This announcement has been in the works for some time, eagle eyed users may have noticed that earlier this month macOS builds were now being designated as "Intel". That's because …

The Current State of Dolphin on Android

Dolphin on Android has had a bit of a checkered history since its inception. Users loved the idea of being able to take their favorite GameCube and Wii games on the go, but expectations and reality have never quite aligned. When Dolphin was first uploaded to the Play Store, developers tried to make it absolutely clear games wouldn't be playable, even going as far as calling it "Dolphin Emulator Alpha". Unfortunately, despite many warnings, many people got their hopes up the moment they saw Dolphin was on the appstore and were ready to play their favorite games, even if their device wasn't. While not everyone had false pretenses as to what should be possible, a lot of users blamed Dolphin for being poorly optimized rather than understanding that it wasn't even meant to run full speed yet.

The endless stream of poor ratings and angry comments eventually reached a breaking point and Dolphin was removed from the Play store mid 2016. That didn't mean development on Dolphin on Android had ceased, though. Instead, builds were provided on our download page, safely tucked away from the majority of users who may not understand the current state of the app.

Suddenly, earlier this month, the Official Dolphin Android app returned to the Google Play Store* complete with all the latest and greatest improvements featured in the Progress Reports!

Dolphin Emulator and OpenGL drivers - Hall of Fame/Shame

In light of the recent announcements by NVIDIA and AMD in support of Linux for their graphics drivers, we would like to share with the world some of the experience we had developing our open source project, Dolphin, a GameCube and Wii emulator for Windows, Linux, Mac and recently Android.

At the beginning of this year, after the successful release of Dolphin 3.5, Markus Wick (degasus) and Ryan Houdek (Sonicadvance1) started working on a rewrite of Dolphin's OpenGL backend in order to be compliant to the OpenGL ES 3.0 standard. While this rewrite was needed for other reasons (it provides the foundations for very cool optimizations), compatibility with mobile devices and the future Android port of the emulator (now in beta) was one of the key goals. This rewrite was merged into the main Dolphin codebase a few months back and started to be used by tens of thousands of Dolphin users, either on OS X and Linux where it is the only viable graphics backend, or on Windows where it is available alongside our D3D11 graphics backend.

Sadly, using recent, advanced OpenGL features also meant we got to discover how bad some graphics drivers actually are at doing their job. It turns out very few applications use some parts of the OpenGL standard we need to rely on to accurately emulate a GameCube GPU. More than that, on Android, OpenGL ES 3.0 support is extremely recent and only a couple applications on the Play Store use ES 3.0 features.

Here is basically our hall of shame of graphics drivers, sorted by the number of issues we found, how hard it is to report issues to the company and how many bugs were actually fixed.
