Got it a week ago and I can't get it to work. I watched countless tutorial video on YouTube.I did exactly what the beginner guide from this site says. And the only thing I see from my ds is "no system file found" or the top screen is black and the bottom one is white. Plus every time I put my microsd card in my compute I can't open it unless I formate it and it starting to get annoying. Anyone knows what to do because right now I'm starting to regret buying this ting. this is everything on the root of my miscrosd. _dstwo(file) NDSGBA(file) _dstwoplug(file) ds2boot.dat dstwoupdate.dat and my ds game file. i even tried to change the "dstwoupdate" to "ds2update" and it still doen't work. Thanks.
