I don't know if the Luma version 6.3.1 is the problem or the updated 11.1 CFW. Because my MH4U (Cart) won't even run. *Launch the game *Nintendo 3DS logo appear *black screen (to load the large memory of the game MH4U/SSB) *nothing appeared after that It never lit my top and bottom screen after the usual black screen of the game. That's why I can't even play MH4U, MHGen, nor SSB. But the game run normally for some reason if I took out my SD Card.
