Because the super smash bros does not want to save the game?

Hello, I’m new with the emulator and I have a small problem … in the single game 3 games, Mario Kart 7, Pokemon Ultra Sun and Super Smash Bros … but the Super Smash Bros always open it does not save the game, unlike the others, if you do, always start it as if I had recently started it, so all my data is lost, and it’s strange because with other games this does not happen … can you help me?

What exactly happens when you go to save the game in Smash?

nothing, just play and when I open it all my data is lost
