Tremendous Mario Sunshine has a TERRIBLE efficiency on Alldocube iPlay 70 mini extremely

Hello, I attempted to play Tremendous Mario Sunshine on the newest model of Dolphin on my Alldocube iPlay 70 mini extremely, but it surely doesn't run effectively, it's completely unplayable. I modified the driving force from inventory to turnip and it didn't work, I decreased the decision to the minimal and it didn't work too, I modified the area from PAL to NTCS-U and didn't work, its the one recreation that runs this horrible, how can I repair it?
