Hi guys. I have a not modded Old 3ds XL (firmware version 8-Europe) and a sky3ds+ flashcard. I've read somewhere that it is possible to install ninjhax 2.0 and run it from the sky3ds flashcard using a Cubic Ninja ROM, without modding the 3ds. The major problem is that the ninjhax website covers the exploit installation only for firmware versions between 9 and 11, while mine, as I said, is firmware 8. However, I found on a reddit post a tutorial on how installing ninjax 1.0 with firmware version 8 (since I do not have the proper rank in this forum, I cannot post the link). As far as I understood, Ninjhax 1.0 does not allow region free gaming, so it is not useful for what I want. Then I wondered if it would be possible to install ninjhax 2.0 with the QR codes for version 8 or (maybe) version 9 or something. My questions are: 1) is it possible to install ninjhax 2.0 with firmware 8 on my sd card using the QR codes for the old ninjhax 1.0, or does it have any chance of bricking my 3ds? 2) after installing ninjhax (if I manage to do it), does the 3ds still boot normally with a sd card, in which ninjhax is not installed (for example, a backup of the original sd card), or is it permanently dependent on the sd card with ninjhax?
