As a Game Boy Advance Emulator
The first public release was version 1.0 on March 13, 2002, and it started out as a Game Boy Advance emulator giving limited support for homebrew and commercial ROMs. The last functional version as a Game Boy Advance emulator was 2.0g, released on March 25, 2005.
As a Nintendo DS Emulator
Martin Korth started working on Nintendo DS support in version 2.1, released on May 17, 2005, even though the emulator could not yet play homebrew nor commercial ROMs. It wasn't until January 22, 2006 when version 2.2 was released, arriving with it both homebrew and commercial ROM support. Support was still in the development stages, and some ROMs ran at a very low frame rate with a lot of graphical glitches; most of them would not run at all.
Version 2.3 was released on August 4, 2006, containing almost full Nintendo DS emulation support, including 3D rendering.
Version 2.3b was released on November 4, 2006 now containing Nintendo DS sound emulation.
Version 2.3d was released on February 23, 2007 adding microphone support and improving 3D video rendering.
Version 2.4b was released on June 5, 2007 introducing for the first time Nintendo DS Wi-Fi emulation, with the application being able to send and receive packets but the information was still getting stuck in commercial games during the transmission.
Version 2.4d was released on August 21, 2007 improving Wi-Fi and wireless local communications being able to exchange authentications on Picto Chat, but the exchange of actual information was still impossible.
Version 2.4e was released on September 3, 2007 adding support for Action Replay and Codebreaker cheats.
Version 2.5 was released on October 4, 2007 being able to run the games at a faster frame rate thanks to CPU and 3D rendering improvements.
Version 2.5b was released on November 3, 2007 adding 3D frameskip.
Version 2.6 was released on December 18, 2007 being able to run games at a higher frame rate thanks to the addition of 3D software rendering such as OpenGL.
Version 2.6a was released on January 23, 2008 being able to run games twice as fast than 2.6 thanks to general optimizations. This version can only be downloaded by making a donation of $2.50.
Martin Korth has not released a new version since January 23th 2008; the cause is unknown.
