what does it do, sorry?

What is that ??? im new in this ö

Hey how did you post a picture from ur 3ds!!

to post a screenshot on 3DS you need to suspend the game then open miiverse and try posting an image

wait no, that's the wii u method, officially anyway, on 3ds there is the image share in the top left menu, where you change brightness, but it was shutdown, luma3ds let's you take a screenshot from the rosalina menu

Yeah whoops probably should have elaborated. I uploaded this screenshot by using Animal Crossing Plaza, that app had a feature where you could put your 3DS's SD card in the Wii U to transfer images, and then you can post them from there

it *SEEMS* to be safe to remove a modded Wii U's SD Card to do this, just make sure you swap them back after :) (also just inherently be careful idk if it could be bad for it)
