So ever since arm9loaderhax has been released, I've been nervous to install it since the installation process requires a downgrade to 2.1. If I were to install it, would I lose my emunand, thus requiring me to reinstall all the data I have on it? Or could I just use another microSD card to install it and then switch back to the one with my emunand on it (after switching the CFW to one more fitting of the new hax)
