I got an Australian n3ds 9.1, sky3ds and gateway, but I don't like having to cary around two carts for every time I want to launch the exploit, + I get card read errors and the exploit crashes A LOT. So what if I just install a EU cubic ninja CIA to my sysnand? I hear that it can brick it, but if it works on emunand it should work on my sysnand right? Has anyone else had success with this? How would I even do this in the first place?
