Super Paper Mario

Super Paper Mario is a RPG-styled platformer developed by Intelligent Systems and published by Nintendo for the Wii. The gameplay is similar to the classic Super Mario games, but with the aesthetic qualities of the Paper Mario series, RPG-like elements like character dialogue and puzzles, and a blend of 2D and 3D platforming. The player starts out with only Mario, but unlocks Princess Peach, Luigi, and even Bowser through the game, and can change between them at any time.

The game was originally planned for the Nintendo GameCube in 2006, but Nintendo changed it to a Wii release due to declining GameCube sales.

Z-Order Issues with Heart Pillars
The DirectX backend has Z-Order issues with heart pillars. Use the OpenGL backend to avoid this.

Pal Pill
The little pals are only visible when you're moving or jumping. If you stand still they become invisible, until you start moving again. After moving through certain rooms (unknown which ones, or if it's just a certain amount), parts of them will be visible when you are still then that part will be cut out off when moving (i.e. the hat shows when idle, but not when moving). Fixed in.

Freeze at Chapter 6-1
In Sammer's Kingdom, the game gets stuck when King Sammer say "Vassals, to me!". The workaround is disabling Bounding Box Emulation when in Chapter 6-1. Be sure to enable Bounding Box again after this chapter, otherwise you'll experience various minor graphical glitches. This freeze doesn't occur if you re-enter Chapter 6 after beating the game. Fixed in.
