Most of it looks like C/C++ code, because it once was. ' The *.D64 file format is a 1:1 copy of all sectors as they appear on a floppy disk.'

The D64Drive.cs file contains the meat of the code to read these image files. There's a file format in the world of C64 emulators that everyone has standardized on called. His app makes frames as fast as they can, putting them in the buffer at 50Hz, and the MediaElement requests frames from his VideoMediaStreamSource as fast as it can take them.

MediaStreamSample msSamp = new MediaStreamSample( _frameStream.Write(_frames, 0, _frameBufferSize) He grabs a video frame from his buffer, he make a sample and reports he's done: private void GetVideoSample() If (mediaStreamType = MediaStreamType.Audio)Д®lse if (mediaStreamType = MediaStreamType.Video) When it comes time to get a sample, the MediaSteamSource calls GetSampleAsync: protected override void GetSampleAsync(MediaStreamType mediaStreamType)

When he wants to write a pixel to his buffer, as he often does at the low level: public void WritePixel(int position, Color color) _currentBufferFrame = _currentReadyFrame _frameTime = (int)TimeSpan.FromSeconds((double)1 / 50).Ticks _frameBufferSize = _framePixelSize * BytesPerPixel _framePixelSize = frameWidth * frameHeight Public VideoMediaStreamSource(int frameWidth, int frameHeight)

He's dynamically creating a movie that never ends.ДЄnd in the code behind he creates a VideoMediaStreamSource the had blogged about here, deriving from MediaStreamSource: _video = new VideoMediaStreamSource(, C64Display.DISPLAY_X, C64Display.DISPLAY_Y) ДЄnd it looks like: private byte _frames = new byte

He was originally creating PNGs or Bitmaps and throwing it up on the screen as fast as possible, but then a member of the Silverlight team suggesting 'making a video.' What did he mean by 'making a video?' He suggested actually using a Silverlight MediaElement (the 'video player' control) and acting as a DataSource for a video. Pete wanted the screen to draw as fast as possible, which is 50Hz (50 times a second). It does have some pretty clever ideas, though, and I thought I'd take a look at those in this Weekly Source Code (which I promise to make more Weekly, starting now). A lot of the code as been ported directly over from Open Source C++ in the Frodo Emulator or from Sharp C64. Keep in mind that this is a labor of love that Pete's doing, and the code has been written in 'gett'er done' mode, so it won't win any awards for aesthetic.

You can read Tim Heuer's blog post for details on how to get started with Silverlight 3 Beta and the tools you'd need or see some video of the emulator in action. He just launched the CodePlex site a few minutes ago (my time), but I've had the code for a while to play with. I had the pleasure of interviewing Pete Brown this last week and talking about the Silverlight 3 Commodore 64 Emulator he's been working on.
