Nothing, that's why you need to follow the second link
Thanks buddy.. It's look that i need get sudoku and steel diver from eshop since my 3ds US region. Sorry for bothering both of you.. >.<The second link doesn't use these 4 pulled games, but tons of another dsiware which is compatible to inject the save of these 4. Look for the "compatible list" in that link.
