So i'm starting to install on my 3DS the games i already own in .cia format. At first the installation times were beareable, with 40 min. for a 1.2 GB game and the likes, but things has been turning progressively worse, to the point that a 700 MB game took 6 hours yesterday. It was insane. I'm using RxTools on 10.3 as CFW on o3DS, and FBI as installer injected into the H&S app. Also, my microSD is a 16 GB class 10.
