Virtu - Apple IIe emulator

Virtu is an Apple IIe emulator for the .NET Framework using C# with Silverlight, WPF, and XNA. Originally developed for RISC OS 3.11 on the Acorn Archimedes in 1995 using some C but mostly ARM assembly language. Published on the cover disk of the October 1997 issue of Acorn User. Later that year we started porting Virtu to Microsoft Windows 95 on the 'PC' using C++ with DirectX. A port to Microsoft Windows CE 2.11 soon followed. These were tweaked over the next couple of years but never published. Fast forward to the present and the latest incarnation of Virtu, this time ported to the Microsoft .NET Framework using C# with Silverlight (on Windows, Mac OS X, and Windows Phone 7); WPF (on Windows only); and XNA (on Windows, Xbox 360, and Windows Phone 7).
