Hello, End 2016 I modified my 3ds with a9lh and was up to date with the latest firmware. It works smooth as butter, I got 3ds games which I converted to CIA with a converter tool and installed them with FBI. This year I gathered some new 3ds games with wii u usb helper. Now I'm confused, because I was up to date with the 2016 developments and now it's a bit different and I have 2 questions: 1: wii U usb helper doesn't download 3ds files which I could convert to CIA, but *.app and *.tik files. It took me a while how to convert the 3ds files with the xorpads and all that. How can I change the *.app and *.tik to cia files for installing? 2: What happens when I install a cia which requires a higher firmware from 2017? Can it screw up my cfw 3ds? Could it for example install a higher firmware and destroy the a9lh? Sorry for the noob questions, the developments are really fast the last years for the 3ds and thanks for the answers!
