I have a N3DSXL on 9.0U firmware. The sysnand is unlinked and everything is setup using Cakes CFW. Recently I read about the IronFall 1.0 hax by smealum and I decided I'd like to download that game as a backup entry point. However, I can't seem to figure out how to create a NNID now. My 3DS complains about updating the system software in both sysnand and emunand. Does anyone know the process to create a NNID? I have all my CIA games installed etc., and boot to HBL using the L trigger.
