I wrote a GameBoy Color emulator in JavaScript ( Open source at https://github.com/grantgalitz/GameBoy-Online ) that utilizes the HTML5 canvas element, so I felt it was only fair to give Pokemon Prism an HTML5 treatment while doing my JS GBC emulator. I present Pokemon Prism for a modern web browser! - http://www.grantgalitz.org/PokemonPrism/ Takes a few seconds to load the ROM data in, so be patient with the white screen for a few seconds.
