smal news update http://code.google.com/p/mupen64plus/
September 5th, 2008: There has been lots of activity on this project lately. The KDE4 gui was modified to be a Qt 4 GUI, so it will work under many non-cutting-edge systems. There have been many QT and GTK GUI improvements. There have also been many changes to make Mupen64Plus more platform-independent, and as a result it is now running (with a few problems) under Win32 and OSX.
