Hacking Need some help with transferring a region changed EmuNAND to SysNAND...

[Bubsy Bobcat]

Since I finally got around to installing A9LH yesterday, I've been wondering how I would go around with transferring my EmuNAND to SysNAND. The problem is, my EmuNAND is EUR while my SysNAND is JAP. Here's how I'm thinking this works:
*Since A9LH installs to the NAND (obviously), I install A9LH to my EmuNAND.
*After installing A9LH to my EmuNAND, I flash my EmuNAND to my SysNAND. Meaning I'll still have A9LH since the EmuNAND I flashed already has A9LH installed to it.
The thing is I'm guessing this is the complete utter wrong way of doing it and I'll end up bricking my 3DS. Can anyone confirm or tell me the actual way of doing it? It seems Plailect's guide goes on about from an untouched 3DS to A9LH.

Just use Hourglass9 to flash the EmuNAND to SysNAND. Hourglass9 will always protect your A9LH, so it doesn't matter if that EmuNAND doesn't have A9LH on it, it will after you flash it. If anything goes wrong, A9LH and your payloads should still work, and you'd be able to boot into Hourglass9 and re-flash a working NAND copy and then figure out what possibly could have gone wrong.
