This happens with things downloaded through Eshop with emunand. 3DS eshop games boot and play just fine, but when I try to close the game out via HOME+X, the system freezes. Booting up a Dsiware game makes the system freeze to a black screen. Whenever I boot back to the Real Nand, all of my downloaded titles get deleted. And they stay deleted even when I go back to emunand.
