JavaScript Gameboy Color Emulator
Prosthetic_Lips writes "A programmer named Grant Galitz has released a GameBoy Color emulator written in HTML5/JavaScript, and it will run ROM images stored locally. What's amazing is that it runs the games at a playable speed. We discussed a different, but similar project six months ago, but it seems like this one is pretty complete at this point. It's also open source."
Well, if you can visit this site on the phone with a modern browser for example...
Just because it's not obscured, doesn't make it open source. The author retains copyright, and still has the right to place it under any licensing terms he/she likes.
