As soon as wi-fi is on and you can verify that you are connected to the internet, scan the QR code I linked inside Cubic Ninja with the boot.3dsx download from the ninjhax website on your sd.
ok inside the sd card i have the launcher for the file boot.3dsx gw-and never other is ok ???
turn on the power of 3ds and wi-fi button launch the gateway screen up on the left internet connection is ok- press select- choose the rom cubic ninja PAL-euro
launch a rom- select create- qr code - i put the 3ds in front a qr code on my monitor and no press button or left or right stick i wait 10-15 second and after 3ds is freeze
ok thanks anyway but here in Italy are 5 am and I sleep try again maybe ok if anything, give me a link if you need
but must configure the 3ds for qr scar or maybe some setting in mii ??
