I just got a new R4DS and tried to set it up and when I turned it on my DS I got a lil blue box on the bottom with what looks like Korean characters (it could be chinese or something else for all I know) and it wont let me touch anything on the screen or nothing I do changes this screen. I took the microSD card out and put into another R4DS card I have and it worked fine, so Im assuming its the R4 cartridge. Is this something that I can fix or is it defective?
