EDIT: apparently someone already asked about CFW, so never mind about that, but still:
If I get these Hacks, could this in any way damage or disrupt ANYTHING in either my 3ds or my game? (ex: online things, Not PVP because I don't care about that)
EDIT AGAIN: Do these work in Revelation. I know I'm being overly cautious, but I just really don't want anything messed up
