HTML5 Amiga Emulator
You do need a beast of a PC to run SAE at a decent frame rate right now. Naturally Chrome provides the best current experience with Firefox a close second. Don’t even think about trying it in a browser that doesn’t support WebGL, WebAudio, Typed Arrays and the FileReader API. So sorry IE and mobile browsers, hopefully your time will come.
But if your rig is capable then even this 0.7 release is quite something to behold. On its site you can pick and play from a range of games including classics such as Alien Breed, Another World, Blood Money, Pinball Dreams, Shadow of the Beast and Turrican 2. There are also demos to view and I personally enjoyed watching through a near faultless full-screen playback of Mental Hangover by Scoopex.
