So I've been out of the loop for a while, and I'm trying to figure out what's the ideal setup to have at this point while retaining my system profile/settings etc. My o3DS is on 4.2 sysnand / 10.4 emunand. I've been using gateway since launch and I've always used the MSET exploit to get into emunand by doing into settings > profile > DS profile. I have a n3DS on 9.0 sysnand. I would like to transfer my o3ds emunand to the n3DS, and start using a9lh/luma on newest firmware, in addition to gateway. What is the correct/easiest way to accomplish this while getting a9lh/luma on the n3DS as well? Would I have to install a9lh/luma on o3DS and fully update before transferring to the new system? Is there any point to having emunand anymore, or do most people just use a9lh/luma and sysnand only?
