So after being undecided due to the fact that my n3ds won't work without an SDcard,I decided I will join arm9hax today. Here are a few of my questions though. Can I restore a nandbackup if I do not like arm9hax? Should I use emunand at all if I can just update sysnand without the hax ceasing to function? What is better aurienand or cakesfw? I will eventually be buying an r4i Do both cakesfw and aurienand let me update my sysnad without patching over firm 0 and firm 1 so my arm9hax still works? How long does it take on average to get the hax done? Does closing the n3ds on 2.0 cause a brick?
