I've had this copy of Majora's Mask for about a year but this is the 1st time in a while I've played it. When I opened it up it had no save data. I played up until I learned the song of healin and then saved at the owl and turned off the N64. But when I started it up again my save file was gone. I tried to play it again and got the same result. Any way I can fix this?
