I looked through every thread and none of them didn't really answer the questions that I have. My questions are down below.
1) When I try to import my save data for Y it doesn't seem to work. Is there something I did wrong?
2) What is a .ekx file for? This is probably a newbie question haha...
3) My current firmware on my 2DS is 10.3.0-28U and I tried to trade with my sister but an error popped up. Is there something I need to do first?
If the questions I asked sound dumb, you can just disregard them and lock this.
