Hey, I have an R4 and have spent many hours playing games and having fun until it broke. It just can't be read by my DS anymore. I put it in, turn my DS on and nothing. It does not recognize that I even have a card put in slot1. I still have a working memory card, that's not the problem. I tested the memory card on my computer, it still works. I even used my friends R4 and my memory card worked in that. So I decided to cut my losses and get a new slot1 card. I did some research and think the SuperCard DsTwo is the best option for me. The big question I have before I spend any money, however, is if I can keep my saves from my R4 card. Does the SuperCard DsTwo save files the same way the R4 does? If not is there anyway I can make my saves readable by a SuperCard DsTwo? If there is no way to do it I would rather buy another R4 just to keep my files. Also does the SuperCard DsTwo require a fast SD card, like the supercard 1 did? My friend had problems with his supercard 1 and needed to buy a smaller faster SD card then the one I'm using. Any help on this question would be great. Thanks.
