Gateway requires cubic ninja or oot every time you power off the console
Whoa, how did I miss that?
lemon07r dude, you can't sell your Sky3DS or Cubic Ninja later on. You'll need to use it EVERYTIME to boot into Gateway Mode on the N3DS XL. If you power off, you'll need to execute the exploit again within CN to boot into Gateway mode.
Nonetheless, you can keep your 3DS running in sleep mode and never turn it off, but even then you can't just sell your Sky3DS or Cubic Ninja coz if you do somehow power off, you'll need it again to boot into Gateway mode
