I might have screwed up.

So recently I've been doing some DS things on my 3ds. But, as of about 1 o'clock today it will no longer boot any DS games! (Unless it's the cart) I now also have to boot off of emunand. Maybe it's because I installed BOOT.NDS to my home screen I don't know. If anybody can help please reply. It goes to this screen. (That isn't my picture I just didn't want to crash my 3ds again)

Run TWLFix then update your 3DS from the System Settings, one or more DS-mode modules might be missing.
