The PCC2 Web Battle Simulator is a port of the CCBSim (DOS) and PlayVCR (Windows/Linux) desktop applications. It runs entirely in your browser. It contacts the server only to download shiplist data and to load/save simulation files; all computations happen on your computer.
It works best when your browser supports Web Workers (IE 10, Firefox 3.6, Chrome 4, Safari 4). Without Web Workers, it will still work, but much slower. A browser that supports LocalStorage is recommended (IE 8, Firefox 3.5, Chrome 4, Safari 4).
The layout will be totally messed up in IE 6, and I've given up fixing that. Otherwise, it should run in every browser newer than that.
VCR Playback
The "classic" VCR Player has the same requirements as the simulator.
The FLAK Player requires WebGL and related technologies. Those should be available on IE 11, Firefox 24, Chrome 33, Safari 8; sometimes also on older versions. Your video drivers should be up-to-date.
