Hacking is rein dangerous?

I wanna save my Animal Crossing gamesave to a backup if my sister happens to lose the game, can I somehow mess it up? I never used this program... can it damage the card somehow?

Can you point me to a tutorial on how to use it? the files are in japanese do I have to boot it in DS mode and change the card later? I'm Using a M3 with passcard 3 setup

I think you are talking about Rain, and if so, here is how to use it:

EDIT: I just noticed the guy changed the name of the program

lol Anyway, it's the same thing, but that guide is a bit out dated.

All I get is 2 black screens... Am I missing something? does it need to be flashed or can it work with a passcard?
