Hi, brother！Have you considered adding rewind function？

I am a player who loves ACT, but my level of operation is quite poor. Seeing NesDS next door supporting this feature allows me to start over even if I make a mistake, which gives me the courage to face the game. Currently, I plan to explore Wario Land and GRYZOR, but just the beginning made me despair, so I can only try to find you for help. May I ask if this feature is easy to implement...
