So I have a very, very stupid question for all of you.
I just got my very first 3DS; it's a "new" 3DS XL. I went to 3ds.hacks.guide and followed the instructitons there, and I seem to have the cfw working correctly. Now I just need games.
Don't worry, I'm not going to ask where I can download them - this is a much stupider question. Here it is: how do I install the games after I download them? I have downloaded some .cia files, and I'm not exactly sure what to do with them.
Bear in mind that this is my very first time using a 3DS - I have literally never played a single game on one, either with a cartridge or a cia file. In fact, this is embarrassing to admit, but... earlier, when I first sat down to look at the thing... I mistakenly put an SD adapter into the cartridge slot, thinking that the 3DS read SD cards of the non-micro SD variety. Sadly, I am not even joking about that one.
Anyway, any help will be greatly appreciated.
