So I want to play Super Mario RPG but the only way I have to play it currently is through an emulator. Fair enough. ZSNES is making this a big ol' pain, however. First the sound quality was horrid, although finally I managed to fix this by turning the sampling rate all the way down. Now the framerate is really jumpy when there's a lot on the screen.

Is there some sort of setting I should be setting that I am not?

Is there a better emulator out there than ZSNES these days? Linux availability is a big plus so I don't have to partition hop.
