I just use emunand however to access the eshop. I dont think as of right now its possible due to the 9.6 update that breaks emunand, but you can download the gateway.dg downgrade file to downgrade to 4.2 from 9.2, and inject your 9.2's nand backup into the emunand partition.
So when this supports 9.6 emunand, I can buy things off the eshop and download DLC and the changes will be mirrored in sysnand, correct? Also; hardware mod for nand backup/restore: Good idea or more dangerous than regular chance to brick?
