ok im planning on buying a dstwo flashcart for my 3ds. but i got a couple questions. i heard somewhere (im not shure where) that it has on board extra ram or something so it can run gba games. is that true? What if nintendo updates can you update your kernal to make it run agin? and lastly if your allowed what is the cheapest website you can buy one from in the usa? and thanks also is it the best card for the 3ds in your oppinion?
