First of all, I need to thank @Apache Thunder who gave me light to this idea. Hello tempers, maybe this is usefull for some, and not a deal for others, but I did it because I was bored and some will want to try the upcoming Ninjhax 2.0. With this method you won't need a Cubic Ninja Retail copy, only the .cia. You need: Latest version of RXTools -with pasta-, you can find it here: http://gbatemp.net/threads/release-...olkit-fw-2-0-9-2.382782/page-338#post-5573757. A .cia format copy of Cubic Ninja, doesn't matter the region, JAP, EUR or USA should be fine. Ninjhax necesary files and setup also here: http://smealum.net/ninjhax/ Steps: Download and setup RXTools with pasta acording this tutorial: http://gbatemp.net/threads/tutorial-installing-rxtools-custom-firmware-3ds-and-2ds.390867/unread Once installed, run the entrypoint of your preference and go to the tab "Advanced". If you followed the previous RXTools -with pasta- tutorial, you should have your title installer already (FBI,BBM,BRM or Dev_Menu). Install Cubic Ninja while in devMode, it's very important or you won't have it installed there if you do this on EmuNand. Once installed, open it and follow the steps for Ninjhax. On the QR generation part, enter your firmware number, and the last letter, wich can be either E, U or J, choose the one matching your cia region, not the console (i.e. I'm using a US 3DS, my cubic Ninja is EUR, so the letter I used to install Ninjhax was E). A garbaged screen should appear, be patient and wait, it takes around 30s to 1min. Ninjhax should be installed now. As a very important note, you should launch it always on Devmode through RXTools, since it doesn't lock any vuln of the 3DS and let's Ninjhax take advantages such as Dynarec wich some homebrews use, like the GBA emulator. Images coming soon.
