Mupen64 has been updated!!! Here is what the author has to say:
"After almost 10 months without any release, 0.4 is finally out for windows and linux. There's no OSX release currently because the porter of the older versions isn't interested in working on it anymore, but if anyone is interesting in continuing his work, please contact me :)
This release includes a whole new core based on a dynamic compiler with a register cache. So, it should be faster than the previous version even if it can still be improved: fpu opcodes are not compiled at all for example. Another new feature you may enjoy: you can record mupen64 movies and convert them to .avi. Of course there are a lot of little fixes and general speed optimizations besides the dynarec but it's been too much time to remember everything. So i'll stop this post here and i'll let you enjoy the release ;)"
You can get it from here.
