Javascript: Scripted Amiga Emulator 0.9.20
Rupert Hausberger's "Scripted Amiga Emulator" is written in JavaScript and HTML5. The goal of his project is to make "Amiga Classic" emulation available in browsers. It is designed to work without requiring any browser plugins or third-party scripts.
Among the numerous changes in version 0.9.20 are the inclusion of AROS ROMs and the fact that emulation pauses when the window is covered.
