I have an old 3ds with the firmware listed in the title and wondering about how I'd go about installing homebrew and what not for my nephew. All he wants to play is the new Pokemon Dungeon and a few other things. Originally I got him a Sky3ds but with the AP blocks I am unsure where to turn, would I follow this guide: https://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/ and just use a Cubic Ninja rom to homebrew it and put xtools on it? Or do I go buy a Gateway?. TLDR, I am just a little confused on what I should be doing and any help/advice would be greatly appreciated.
