==History and development roadmap==
The JSMESS project was originally proposed in a [http://ascii.textfiles.com/archives/3375 October 2011 blog post ] by Jason Scott (of textfiles.com and The Internet Archive in October 2011.[http://asciiwww.textfiles.com/archivestextfiles.com] and [http:/3375/archive.org/ The Internet Archive] ). The idea was to have a system for preservation of old computers and game consoles that runs directly in the web browser without any plugins.
Initial progress was slow because the Emscripten transcompiler had to be fixed and improved during development. In 2013, JSMESS reached a fairly usable state and was declared to be in public beta.
