recovering files from a corrupt sd

[hyeegoist]

Hi everyone! I made a post a few months back about recovering my data from a corrupted sd. I'm in the process of doing it now, what is the absolute basic things i would have to save? Like, my saves and everything... I've already recovered my ds game saves but idk if the 3ds saves are in the sd or the console saves them locally?
Also I assume i would have to follow the tutorial to mod the new sd and then add my saves then right?

also how would i add the saves to the re download of the game? do i just copy and paste?
