I have a EU N3ds with Sky3Ds and Gateway. I would like to update my Sysnad to 9.4 so I can play Xenoblade in Sky3Ds without having to do use gateway (do the exploit and then close and open the lid everytime is really annoying). Is it safe to use Xenoblade in Sky3Ds to update my sysnand (and perhaps my emunand) to 9.4?
