So I was transferring games to my Stargate when all of a sudden it stopped working. It just did not load the games anymore. Ofcourse I panicked! First thing I did was look online to find more people with the exact problem. Returning is not an option while it costs to much... Here is how I fixed it: I simply inserted another SD with the files on the original SD in the Stargate 3DS and that fixed it for me! I have made a small 4GB MicroSD now with 1 game on it and insert that when the problem returns. What is happening? I really don't know. Just hope this fix helps more people with the same problem.
