Iḿ a little annoyed at this. I would like to use my dstwo for my dsi and 3ds but it doesnt show up. It showed up every time before I opened up the gateway installer on my dsi. It still runs fine, although I can get into it 1/30 times ive taken it out and put it back in. I heard its a thing that I have to clean the copper tips at the end, but im not sure if thats gonna make it worse or not. Thanks everyone. PS: I wouldnt be afraid to break into the thing if it came to that.
