Theres a little story here. A few years ago, a friend of mine loaned me his dsi as he went around the country. I was lead to believe that it was now mine, but he eventually wanted it back. He did get it back after some fuss, I won't go into detail about that. Anyway, during my time owning it, I bought several DSiware games for it. I thought I would have to rebuy them when I got my 3DS, but I've learned I can transfer them from a dsi. My biggest concern with this is will he keep the games on his dsi? Or is everything transferred to me and he loses everything? I want to play them again, but I don't want to mess him up. He plays them too.
