Hi GBATemp. After getting my Sky3ds some days ago, I used header from Super Mario 3D Land and patched it using NoBanNoSky. But it didn't work on any of my games. I used Sky Army Knife and others but they didn't work too.
So I finally found a way 3 days ago, and was testing many different games- like Mario Kart 7, Super Smash Bros and many others before releasing the way how I did it. IF NoBanNoSky DOESN'T WORK FOR YOU, OR YOU ARE GETTING ERROR 002-0123, THIS IS A TUTORIAL...
