Elecbyte is the developer of the M.U.G.E.N game engine. Elecbyte consists of 3 programmers, DFW (David), K'Style and R.
DOS and Linux Versions (1999 - 2003)
First released on July 17, 1999, M.U.G.E.N was initially created for MS-DOS. Development of the DOS version ceased when Elecbyte switched to the Linux platform in November 2001. For a time, Elecbyte had posted a request for donations on their site to legally obtain a Windows compiler to make a Windows version of M.U.G.E.N. However, the development group discontinued the project in 2003 and shut down their site. Later speculation pointed at leaks made public of a private Windows-based M.U.G.E.N beta that was provided to donators.
Windows Version and Subsequent Hacks (2004 - 2008)
With Elecbyte no longer around M.U.G.E.N was left abandoned. The private WinM.U.G.E.N beta contained a two-character roster limit, locked game modes, and nag screens. With the beta leaked and Elecbyte gone, a "no limit" hack that removed most of these limitations was made available in 2004 by Rou Hei, followed by subsequent updates to deal with bugs and other issues. This version of M.U.G.E.N. is functionally the same as the last Linux release, though with subtle differences and unique issues, mostly revolving around proper music and music plugin support. Because of the changes between the DOS and Linux versions of M.U.G.E.N however, many older characters required at least the SFF files to be modified to show palettes correctly as well as some changes in how certain CNS script controllers functioned.
Throughout 2007, various edited version of WinM.U.G.E.N was released by various third parties that added a variety of features for high resolution graphics, culminating in the release of WinMugen Plus which features support for a high res select screen, as well as both high res an low res stages support. This remained the standard for M.U.G.E.N users up until 2011.
New Elecbyte (2009 - current)
In 2007, Elecbyte's website reopened with an F.A.Q. regarding mugen. The F.A.Q. claim the intention to release a fixed version of WinM.U.G.E.N before major format changes in the next version, and noted the formatting changes would remove compatibility in regards to older works: "Do not expect old characters to work. At all." They also stated that a new version of M.U.G.E.N would be out "when 2D is back in fashion".
In 2009 The elecbyte.com domain was purchased and updated to include an early beta version of Mugen, along with a new forum and document Wiki. A new development team has emerged and has released 8 different release candidates for a new mugen game engine leading up to the January 2011 release of M.U.G.E.N 1.0.
