SNES Classic trick for beating difficult Nintendo games

> Or you can rewatch up to a minute (depending on the game) of your gameplay before you hit suspend, then pick up the game from a moment before you saved.

This reminds me of http://nintaco.com/, a recently released NES emulator with an infinite rewind ability. It is apparently implemented with a mix of save states and a recording of controller input which allows to reduce memory usage by just having to replay the input since the last save state.

I would be curious to know if the SNES Classic uses the same trick, although I suppose they don't need it as they probably don't support going very far back in time.
