The moment I got my Supercard DSTWO Plus, I began to do various testing on it to verify its "super ability". Firstly, I tried to use it to play 3ds roms on my 3ds console. I was frustrated at first since my several attempts all came to be failed. So why ??? Naturally I searched a lot on the internet in the hope of finding some answers. Finally I saw a video display as below saying that "you must put Gateway 3ds 'Launcher.dat' into the SD card!!!!! " What a timely and yet soooo funny/comical answer !! By operating it in person, it's not difficult to find that apart from the card itself DSTWO Plus is more like the variation of gateway 3ds.
