Kirby Super Stars Ultra loading problem

Can anyone play this game? I've downloaded the game numerous times and i keep getting "cannot save the game, reinsert the game card". or something like that, how can i fix it? Thanks

If you are using a flash card, update your firmware.If you are playing on the emulator, change the save type and reset the cartridge until you find the one that will make your game work.

thanks man, i will try it
