Since the release of gateway 3.2.1 for the new 3ds we can now install the old system menu to the new 3ds allowing the use of the ds profile exploit to be used again thus no longer needing to own a copy of cubic ninja or ocarina of time. I am making this thread with the hopes that a few other trusted people in other countries will throw their hats in the ring and help others out too.
Here is how it works, depending on the country you are from contact the person via PM and ask politely if they have the time to install the NVram exploit / blue card fix for you. You will then send them your n3ds along with a prepaid return shipping label Make sure to insure the package both ways! They will then install and return your n3ds. I will also include the n3ds regions you can personally mod in case you only have a retail EUR OOT for example.
