just press the home menu and open miiverse!

i meant home button

Is there a way for 3ds? i know i can take screenshots with rosalina menu but i dont even know how to view them

i dont have a 3ds but i'd assume theres a homebrew app with viewing files on the sd card? there is one on wii u

if you hold X on Miiverse once your in the page you can let go thats how it worked for me

welp, first, there arent screenshots on 3ds, but they do exist on wii u, when playing a wii u game, if something that you wanna post shows up, open up miiverse from the home button menu, and then tap "add screenshot" when making a post and exactly whats on screen will appear!

P.S: if you do include a screenshot, you CANNOT include both a drawing and text, its either one or just the shot.

P.P.S: if an app just quits instead of showing the home button menu when pressing the home button, you CANNOT take a screenshot of it. so ummmm... yeah, no mii maker here, also, you also CANNOT post one from the vWii, because ofc, its an different environment from the wii u.
