I haven't installed CFW on my 3ds yet, mostly because I don't know the details of what all it does, good or bad. I'd like to use my Acekard 2i on my 3ds, even though its been blocked for a long time. I thought it would be pretty easy developing a simple homebrew tool for that, seeing as it's easy to remove region locking, but I could be dead wrong. Please reply with any information that could help.
