I have a DSi, and on flipnote hatena someone said there is a bunch of buttons you can press to go to a "hacking screen"? Answered
The flipnote says to turn your dsi off then turn it back on and before it says "Nintendo DSi" type: Y,right,right,X,up,down,down,select,up,down,left,right,up,R,L. Then you supposedly go to a hacking screen. Is this real because, I couldn't input the buttons that fast.
