Most good emulators have a frame advance/stepping option. The best thing to do (for any animation, but especially fast ones) is to pause (the emulator, not the game) and slowly advance frame-per-frame. This means you can take screenshots of every single frame, no matter how quickly they move in-game.
Obviously it depends on which emulator you're using, but a quick Google search led to this thread which says that Snes9x can do it.
