3dsx and CIA files.

Remember when everyone was freaking out over the huge banwave Nintendo did a couple months back? Everyone was saying "Use 3DSX files! Don't use CIAs because Nintendo can still what you are playing even with the show friends what you are playing option off!" Well, for about a week, I agreed with them. However, I found it inconvenient to use 3dsx files, so I went back to using CIAs. I have both of the main options turned off (i'm assuming you know what they are), and I've even been using a public LFCSB, because I had no chance when the banwave happened since I was somewhere else entirely without my 3DS. I couldn't turn the settings off. So my way of thinking is that it WASN'T the CIAs, and was just those two options because usually, the public seed doesn't get banned for a few months. Something else I've been thinking, since one of my friends wants me to put CFW on his 3DS, I might just use his LFCSB to test this theory. I maybe an idiot, but oh well.
