I haven't touched my 3DS in quite awhile and I'm curious what can be done with it in regards to homebrew etc. I was interested in a flashcart, but now I'm reading stuff about running 3DS games from the SD card. Some articles talk about a Gateway being required and some say you don't need one. I've reading stuff about downgrading firmwares too. Trying to figure out where my 3DS stands in all this. I have the O3DS with firmware 9.9.0-26U. Is it possible for me to play 3DS games (CIA files iirc?) from my SD card without the need of a Gateway etc? Hope you guys are having a good weekend and thanks for the responses.
