So I've gotten a bigger SD card, finally, and transfered my files from my old 2GB SD to my new 32GB micro SD. Everything came through just fine, without any trouble - except for the save file of Pokemon Rumble World. The file came corrupted. I've tried three times already, and everything came perfect - except for Rumble World.
I don't want to lose this data, since I've bought 200 diamonds (not much money, I know, but still a luxury to me); and I was already on rank 37. The diamonds are the worst, really. I still have the data saved in the old SD card, but I'm really hoping that there's a way to bring it to the new one - I don't want to be forced to use two SD cards, nor be forced to lose the diamonds I bought. Is there anything I can do?
