I knew you had problems with that Mario Party 9 minigame. Well, I understand, I was frustrated with that for a long time, but after several attempts, I finally found the solution. This guide will help you. However, you will have to pause each round when you see the arrows on the screen and make the corresponding settings so as not to fail in any round. I would suggest you share this immediately, and if possible, also put it on the Dolphin wiki (only if you want). Here it goes:
Settings for the shake in the minigame "Do not look there":
Tip: If you use more than one key for any of the following cases, it is advisable to always use the same key (I use the "3" key).
Look down or up:
X = Nothing
Y = Any key
Z = Any key
Tip: To look down, make a long touch, and to look up, touch and release quickly.
Look to the left
X = Any key
Y = Any key
Z = Any key
Look to the right
X = Any key
Y = Nothing
Z = Any key
