I wanted to format my modded 2ds and simply went into settings and clicked on formatting, but now when I turn it on I see these words. Also, I need the SD card that was inside this Nintendo to do other things and so I wanted to return it to normal and without the SD card

I bought this Ds lite and it has this strange "glitter" effect on the screen frame underneath, even my old gray Nintendo Ds lite had the same effect, I don't like it very much and I saw on YouTube that some are not like that but maybe they are not visible well. All nintendo ds lite have this effect?
