A Gameboy/Gameboy Colour emulator for windows, yes some people are still making them, well it was a fun system. There is no traditional news listing for it just this from the readme:

This is an early beta of my Nintendo GameBoy emulator, GameKnight.

There are still plenty of bugs and missing features such as sound.

I'm putting this out there so that people can test it and to give it an actual website.

Please tell me about any errors you have running the program.

The source code is licensed under the MIT license and can be found in license.txt in the source folder.

To compile you'll need a copy of SharpDevelop 2(Visual Studio might work), .NET 2 and the September version of SlimDX(included with the program).

Note: Save states currently only work properly with original GameBoy games.

Download from the homepage.
