Pokemon World Online.
Not official, but it has been up for a few months now and Nintendo don't seem to be too bothered about it. As far as I am aware, it is an Online version of Pokemon Fire Red. (Note that I haven't actually played it myself.. Just read/watched videos where people have mentioned having fun on it.)
