I've been away from the scene for about a year and I'm so confused. I have a N3DS with 9.2 and a Gateway. Is there a guide somewhere that explains everything? I'm hearing about A9LH. What is that? What do I need to do to get everything updated to the best available way?
Sorry for the noob question, but whats the difference between a .3ds file and .cia? I know you can install .cias to the internal SD card, but what benefit does it have?
