I got an old ds lite and a m3ds real card that has the m3 sakura logo on it too. put the "system" folder on a 16gb sd card, boot up the ds, long press "a" and the only thing it says is the logo at the bottom right corner, "[EN_V1.1_V3]" at the other corner and "slot 1 nds" in the middle. i tried other sakura or m3ds versions and none work. what else can i try?
