select games at full speed for the first time, audio was dramatically improved, and the graphical capabilities were made more consistent aside from minor problems. By late October 2009, several new features were incorporated into the emulator, such as automatic frame-skipping, which increased the performance of the emulator, as well as increased stability of the emulator overall. Also improved was the Netplay feature of the emulator, which allowed players to play multiplayer GameCube and Wii games online with friends, as long as the game did not require a Wii Remote. The emulator's GUI was also reworked to make it more user-friendly, and the Direct3D plug-in received further work. On 12 April 2010 Dolphin 2.0 was released. 3.0 and 3.5 releases (2010–2012) By the end of November 2010, the developers had fixed most of the sound issues such as crackling, added compatibility with more games, and increased the overall emulation speed and accuracy. In June 2011, version 3.0 was released. Strange user interface behavior, crashes, graphical glitches and other various issues were fixed. The release notes state that the majority of games "run perfectly or with minor bugs.” The release featured redesigned configuration windows, an improved LLE sound engine, new translations, added support for the Wii Remote speaker, EFB format change emulation, graphics debugger and audio dumping among several other new features. The 3.0 release removed the plug-in interface in order to “allow for a much better integration with the other parts of Dolphin.” The developers also added a Direct3D 11 video back-end and an XAudio2 audio back-end. On 25 December 2012, version 3.5 of Dolphin was released, featuring support for emulating the GameCube Broadband Adapter and Microphone accessories. It introduced a FreeBSD port, free replacement for the DSP firmware, and the WBFS file format. Port to Android and 4.0 release (2013) On 6 April 2013, the Dolphin development team released the first builds for Google's Android mobile operating system. As of September 2013, only a handful of devices contained the hardware to support OpenGL ES 3.0, with Google officially supporting the standard in software since July 2014 with the introduction of Android 4.3 Jelly Bean. Games ran at an average of one frame per second. The developer has cited the Samsung Galaxy S4 as one of the first phones capable of playing games at higher speeds, but even it would have considerable performance limitations. On 22 September 2013, version 4.0
