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: July 2015


Since the release of Dolphin 4.0, things have advanced quite a bit. With compatibility rising to their highest levels yet alongside features that seemed impossible and extravagant, users have been asking about the next stable for almost a year now. For previous releases, including Dolphin 4.0, the staff mostly ceased work on new features while crashes and regressions were addressed. In the case of working toward Dolphin 5.0; there were just too many interesting and exciting features on the way to risk stalling out by asking developers …

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!

Relicensing Dolphin: The long road to GPLv2+


Since its resurfacing as an open source project in 2008, Dolphin has been licensed under the GNU General Public License version 2 (GPLv2). This license, created in 1991, is still a fairly common license used in the open source world. But as with anything that deals with technology, times are changing at a rapid rate. More recent projects are using GNU Public License version 3 and Apache 2.0, for their additional freedoms, protections from outside liability, and improved inter-license compatibility. Unfortunately these newer licenses …

A Second Perspective: An In-Depth History of Stereoscopy in Dolphin

Videogames are interactive experiences with emotional highs and lows, providing players with thrilling experiences alongside wondrous vistas. The greatest games can leave lifelong impacts on their players long after the controller is put down.

Emulators serve as a convenient way to relive those past experiences and rediscover hidden gems from one's childhood. But what if an emulator could not only recreate those moments, but enhance them by pushing the games you know and love to new heights? At what point do people say that the must-play …

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.

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

A Commemoration for Rachel Bryk

On Thursday, April 23rd, we lost part of our family. Rachel Bryk tragically died at just 23 years old.

It's hard to believe that just two years ago, Rachel was reluctant to submit changes to the emulator at all due to being relatively inexperienced. But over the course of two years, she spent a considerable amount of time working on what she loved, becoming the tenth most active developer over the time period.

She often would do a lot …

Dolphin Progress Report: March 2015

Progressreportheader-March2015.jpg


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 …

Datel: Unlicensed Product Showcase

datelheader

Software licensing has been a way to control not only the quality of products for game consoles, but also limit what developers could do. From the Nintendo Entertainment System onward, Nintendo has used a variety of lockout chips and DRM in order to make sure all of the products on their consoles had the Nintendo Seal of Approval. Their efforts kept quality much higher than in the previous era of gaming, but did not completely stomp out all unlicensed products and games. For the GameCube, Wii, and many other …
