A possibly n00b question: I want to switch my 3DS from Gateway to Luma3DS, converting my GW roms to CIA. I have 500+ hours of gamesaves for those GW roms, and I really don't want to lose them - is it possible to back them up and make them usable for CIA games? (can anyone link to a tutorial if there's one?) Also, is the switch even possible if my 3DS is on sysnand 4.5 with no games for updating to 9.x? And a secondary issue: will I be able to use my GW blue card on the Luma3DS emuNAND?
