Fire Emblem

I remember playing Fire Emblem on the Game Boy Advance, I think it was the seventh of the Japanese releases, but the first one to get an official English translation. I was right at the end, having nearly completed it, and was so excited that I started throwing my GBA SP up in the air and catching it, with the game still inside. I accidentally missed and it dropped on the floor with a thud. I switched it on to check if everything was OK and as I feared all my save files were deleted! My heart sank; I had to start all the way from the beginning again!
