There were
previous threads pushing this idea, especially for v1.43.
It was announced 3 years ago that users should move onto something newer. Yet plenty of runs kept on being made with v1.43, despite how horrible the sound engine is in that, and that plenty of games aren't emulated quite right, even if you can complete them.
We now have multiple accurate SNES emulators to choose from available on all platforms: lsnes and Bizhawk. They may be lacking certain features you want, if so, ask their developers to add them. You may be unused to their interfaces - get used to it. lsnes also allows you to input during any input frame, even if multiple input frames occur between any two given video frames, making things like the recent Chrono Trigger movie possible.
We are deprecating use of Snes9x.
I would like to say: "You have until December 31 2012 23:59 GMT to complete any runs you have started using Snes9x, no exceptions will be made, unless you have been granted a continuance on your existing run." and: "If you feel you have a long run that already had a lot of work put into it, and will need a while to be completed, you may request a continuance in this thread. We will accept continuances until December 15 2012 23:59 GMT."
But if I said that, some people would probably explode. So I'm not going to say it outright. However, we will be disallowing Snes9x sometime in the future, even though no hard date is yet set. You've been warned.

EDIT [Mothrayas]: As of yet, the current ruling can be found
here. Snes9x v1.43 is, as of now, no longer accepted unless it has been granted a
continuance, or if there is proof that the movie was done before January 1st 2013. Snes9x v1.51 is, for the time being, still accepted.
