In mid 2007, Elecbyte's site returned, though not without some controversy as to the legitimacy of it, as it only showed a single logo with Google ads on the side.[9] On July 26 a FAQ was added to the site, which went on to claim that they would 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".[10] On September 19, 2009, Elecbyte made an unexpected comeback, updating their website with various features — including a forum and a downloads section, where a new build of M.U.G.E.N is now available.
In September 2009 a full release of M.U.G.E.N that includes various new features — most notably (official) support for HD resolutions, victory screens and language localization — was made available through the Elecbyte website. Although this current build has various visual glitches and requires a fair amount of adjustments to the previously made content in order to be fully compatible with the new engine, Elecbyte has stated that it is their goal to have the new M.U.G.E.N fully compatible with previously designed content.
