I remember a while back there was a .nds file that was the system menu for the DS (launch slot 1/2, Download Play, Pictochat etc.), but for the life of me I can't remember what exactly it was called. Obviously I'm not expecting any download links or anything like that, but does anyone remember the file name? Found it! It was firmware.nds, for some reason I was thinking systemmenu.nds or something.
