Motion controls are given an important job in Paper Mario The Origami King. Regardless of if you are using a Pro Controller or Joy-Cons, they control Mario’s 1000-fold arms, used to solve puzzles, open pathways and attack bosses.
While this works relatively well — at least while playing on a TV — it isn’t any better than using normal controls. In handheld mode, moving your own arms (and the screen) away from you to move Mario’s arms isn’t very practical.
Fortunately, it is possible to disable motion controls and use the control stick to manoeuvre Mario’s 1000-fold arms instead.
To turn off motion controls in Paper Mario The Origami King, press the Plus (Start) button and navigate to the menu cog icon on the right-hand side of the menu. Motion controls is an option to toggle on or off.
While it’s fairly easy to find, the game frames motion controls as a mandatory feature — but it’s completely optional.
