I know the tutorial says to use Decrypt9 but if I was you, I would use a program called 3ds Lazy, which is a lot more user friendly and I've been able to get the xorpads without any trouble, using it. As for savedatafiler, just drag the .cia file to the root of your SD Card and install it with either Devmenu or BigBlueMenu on your 3ds. Hope I helped you a little. ^_^
