Had this new 3ds for a while but never used it cause it needed a battery replacement. So i recently ordered the battery and got it onto the n3ds, seems to work well, started up normally without issues, still have to test the battery life to see if the battery is any good or not.
Well i tried to change the micro sd card inside for the one i use on my regular 3ds (the 3ds ive been always using), but i got this screen when turning it up, what should i do?
