or you install them from the nightly ppa and help testing

 I looked at this route but it seems like most of the emulators failed to build.  It looks like there was a missing dependency, but you would know much more than I would about that.  I installed virtual-jaguar and fbalpha from ppa and they work well in the little bit I've played around.  For snes9x and beetle-psx I had to build on my own.  I can report these findings on github if you like.
