Ok so i did the above about a week ago and i want to rid my emunand on sdcard and just use it with 3ds system and games/saves. I currently use newest luma3ds, would i just need to backup everything on sdcard, format it to fat32 than just transfer the newest luma,a9lh.bin file and any game saves to root of sdcard and i wont lose anything right? Main thing i dont wanna lose is my game saves after i format sdcard, but i should be fine as long as i backup and copy them after format.
