There is still activity. 1964 is most likely due a final release, Rice is still improving his graphics plugin, there was a new input plugin released a short while back, Orkins GLN64 is still astounding, and Glide64 is also continuing to be in development. Also Mupen is one to keep an eye on, it has improved significantly in the last few versions.
Eventually those features you want may make it into a plugin, but at the moment no developments for these features are known about.
