Yes you can use a different SD. One SD for your region and one for the Japanese oneThank you so much! I'll give it a shot tomorrow.
Edit
Quick question instead of dual booting can I just change the region on a separate SD that I have emunand on? I would just have to get luma cfw since I already have arm9 installed right?
Sorry for the noob questions lol

I used HANS to manipulate my ROM on a Japanese 3ds to get the event Pokemon. Are mine illegitimate? Because I can tell you I don't wormadam.
Yes. You need to have an emuNAND setted up on it, obviouslyOn that note I can just copy paste content from one SD to another to maintain A9LH/Luma, Sysnand unaffected?
I did not notice that he had a section for that on his guide, follow Pailect's guide, its cleaner than the older one, just do any changes to emunand (unless you want to lose the eshop)So Plailect's guide has a region change section, but for CFW sysnand. Can I also use that for emunand? Or should I follow the tutorial on this site?
