It should move a lot faster on that, but I still suggest taking your time. I've installed A9LH on several 3DS's myself, so it's become second nature to me, but if this is your first time install it, take your time. I seriously can't stress enough that you need to make back up of every single step and make sure you read every step before jumping around.you talking about a class 4 says I should probably bring up the fact that I'm using a 32GB UHS micro sd it only has like 2GB of games on it though as most of my files are in the sky3ds
My actual first install took well over 3 hours on my personal 3DS.
