I can highly recommend this project to anyone wanting to get their feet wet with emulator programming, video-game programming, or even cross-platform development. It has been a great educational excercise involving major aspects of modern day applications such as input handling, user-interface design, 2D graphics rendering, audio generation, code profiling and more.

Enjoy!
