Added a link to World of Spectrum, I'll test a few emulators too. You can find a ton of them on the site for nearly every platform from computer oses like windows and linux, to smart phone oses like android, iphone and symbian, to handhelds like the ti89, palm, psp, and the ds to consoles like the dreamcast and the wii. But I need to pick out one for the main post, preferably one that's cross-platform.
