Comment 1 for bug 877073

It does seem like these claims are dubious. Snes9x is still updated upstream and has a public github repository, while the zsnes upstream hasn't changed in almost 5 years. Claiming zsnes is an alternative clearly suggests personal preference, as it doesn't nearly approach the same accuracy as Snes9x, and a better (still free) alternative, bsnes, exists and would make a more applicable replacement.

Still, there's not much one can do when an opinionated maintainer makes a decision. I'm updating my PPA with packages for natty and oneiric now. I'll try to keep it more up-to-date since there are no official packages anymore.
