I hate this problem! I have already switch the save type to Flash and Flash 128k, but it still doesn't work. (Automatic + Flash 64k tested, but the problem is still there.)
1. 0:14 - "The 1M sub-circuit board is not installed."
2. 0:39 - "Warning, there's already a save file."
3. 0:51 - "Save error. Please exchange the backup memory."
