From what I've read, in order to downgrade the MSET, it requires a copy of Cubic Ninja or Zelda OOT. I plan to set up reiNand on my Japanese imported N3DS and am not sure whether or not I should purchase Cubic Ninja and just run reiNand through that or a flashcart if the N3DS MSET is downgradable. What exactly do I need to set up the MSET profile exploit on my N3DS? Thanks.
