Thanks for replying!
I'm a little lost with option 2. From reading that guide, I'm to use a NTR CFW 3.0 to get this to enable that?
I bought on eBay the Fire Emblem IF: Special edition (JPN), New 3DS with 9.2 Firmware with current setup on the 32gb micro SD set to autoboot ReiNand CFW through menuhax. The emunand is on latest 10.7 and has a title manager already on it, and Cubic Ninja. So with these then, I just need to setup that NTR CFW 3.0 to be able to get on the Japanese eShop then?
Finally, if I managed to get this to work, I'm assuming I need to setup an Japanese eShop account through the main game via Dragon Portal when I buy the DLC or through the Homebrew interface? Also, do credit cards outside of Japan work or do I need to go to places like Play-Asia to buy a Nintendo points to use?
My apologizes if this was long or if this was asked. I did my best to search from this site and Google to get an answer, but I wasn't finding the answers I was seeking.
