So I finally got my Gateway to work and I'm playing ATTACK ON FREAKIN TITAN on my US 3DS! Aside from the cheap crappy 8GB micro SD that came from Taiwan and broke right away and the fact that you need an SD and micro SD reader I'm happy with my Gateway. However, I don't know if I should downgrade to EMUNAND 4.5. Once you do EMUNAND (I'm still on NAND 9.0) and downgrade to 4.5 I know that you can play online and go onto e-shop etc... but do you still have to turn off your wifi and worry about accidently upgrading? Or once I launch GW mode and downgrade am I good? Also is the blue card that came with my GW just for .nds files and nothing else?
