Nice list.  I do wonder how useful they are though, given that the actual ROMs for many games are illegal to distribute and the emulators require them to work.  Are they for people running a personal server on their computer? For websites that want to let people play homebrew games through the browser?<p>Seems like the list of uses for a Javascript emulator isn&#x27;t particularly high.<p>But they&#x27;re pretty cool on a technical level.
