Ok I just got a FireRed from a friend today. It looked perfect and ran smoothly. But when I tried to save, there was a saving error and the game crashed. When I restarted it, it said "The 1M sub-circuit board is not installed." So I played a new game until I was able to save, and then it just said "Error. Please install backup memory" or something like that. Keep in mind that this is a cartige and not an emulator.
