jsc64 is a Commodore 64 emulator written in JavaScript by Tim de Koning. It's a port of the FC64, the Commodore 64 emulator written in Actionscript by Darron Schall and Claus Wahlers. This emulator is meant as a 'proof of concept' and uses the HTML5 Canvas-element to render the Commodore 64 screen layout. It will work on all modern browsers like Firefox, Google Chrome and Safari.
