I want to play the restoration mod for Majora's Mask for the 3ds, that'll fix some issues with the game. However, for the mod I need to use a custom firmware of Luma3ds and copy it to my NAND. I do have Luma3ds on my modded New 2DS Xl, but I'm not sure how to do this. How do I install the new Boot.firm and copy it to my NAND? I already have the new Boot.firm on my SD card.
