I got an M3DS real and I cannot get it to boot sakura or the quad boot, I can boot fine and get to the menu with the files from "G6&M3DS-R_M73.zip" which i think is the newest official firmware. If using the quad boot or sakura it will boot and show the m3 logo in the corner and then just go to a black screen, I saw someone said to hold a on boot and all that does is show some text on the bottom screen saying slot 1
