Some more testing uploaded:
Mario Kart 8 - Shaders load completely at the first race.
Zelda Wind Waker - Little bit tricky to type in a name while creating a new savefile. Black flickering on characters are gone.
Yoshi's Wolly World - Hangs after displaying the controller screen.
Zelda Twilight Princess HD - More or less the same. Have been playable for good while now.
Super Smash Bros. U - Sound is better.
Super Mario 3D World - Look's overall great, besides for some levels, like the first one I jumped into with the mirrors.
