First, sorry for the crappy video, but i almost never upload something to youtube
Uploaded a Video of Cubic Ninja retail cart and Sky3DS. (N3DS XL FW 9.0.7-25E)
As you can see on the end, i press the HOME button to show you the freezing and how to get it fixed (Yes, just remove the game cart ) without pressing long the power button to turn (N)3DS off
This video shows regionfour working with Cubic Ninja and an out of region game, both on Sky3DS, The out of region games is written right behind Cubic Ninja, if not it will not work. (N3DS XL FW 9.0.7-25E)
Great video.
I put three games on my sky3ds (using in my n3ds 9.7 US):
Cubic Ninja (US), Mario and Luigi (EUR) and Mario Vs Donkey Kong (JAP).
I run Cubic Ninja to start the regionfour and when show to change the game and press start, I press the blue on my sky3ds and wait the lights stop blinking. Now the game loaded is the second game on my sd (In this case, Mario and Luigi).
If I what to play the third game (in this case, Mario vs DK) I just press the blue button again and wait.
Finally I press the start button and play the game.
