Hi, I'm very interested in this! Could you explain EXACTLY in idiot proof instructions how you do this? I've got a gateway and emunand and installed various cias (all non legit) but I'd like to try putting some legit ones on that show up in sysnand.
No worries if you can't be arsed!
r
first install the legit cia in emunand until its successfully installed using bigblue or devmenu.
next turn off and turn back on your system and proced to the exploit that loads gw 3.1.2 without having the gateway inserted
next insert the gateway and hold on the B button while selecting the boot gw mode menu, it should say boot gateway sysnand and after accepting it should tell you to press X to proceed.
then once loaded press select and load devmenu or bigbluemenu and run it, assuming your preferred cia installer is on your gw cartridge sd.
install the legit cia's from the first step but instead of waiting for a lot of time you will just wait for a few seconds until it says installation failed software already installed.
once you do this for all your legit cias you installed, press the home menu and a 3ds pop-up message will appear saying new software installed and the software being the cia's you installed.
feel free to turn off and on your 3ds again to see that they are playable in system nand.
I find this installation method much safer than simply installing to sysnand because it gives less chances of error occurring during installation and less chances of bricking.
