Super Mario Galaxy 2

Super Mario Galaxy 2 is a platforming video game developed by Nintendo for the Wii. It was first announced at E3 2009, and is the sequel to Super Mario Galaxy. It was released in North America on May 23, 2010. The game's levels are galaxies filled with minor planets and worlds. While its gameplay is based on that of its predecessor, the game was updated with gravity effects and new power-ups. It is the fourth original 3D platformer in the Mario series, after Super Mario 64, Super Mario Sunshine, and Super Mario Galaxy.

Freeze After Grand Star Levels
Upon finishing a grand star level, the screen may go black, preventing you from saving or continuing. There are two known solutions to this problem.


 * Use DSP-LLE (also solves other sound problems, recommended)
 * Use DSP-HLE with the Xaudio2 backend

Note that using savestates during one of these levels may cause the problem despite these fixes. To avoid a hang after loading a state select "Audio Backend: No audio output".

Framebuffer Errors
Framebuffer errors are occurring with the OpenGL plug-in on nVidia cards and ATI cards with anti-aliasing options enabled. Use the DX9 or DX11 plug-in to avoid the errors.

Music Cuts Out
Background music cuts out after a few minutes of play, as a consequence, it appears that the end credits of the game do not play, making it impossible to create a cleared gamesave. Use the DSP LLE plug-in to correct this.

Wiimote Lag When Collecting Starbits
Wiimote slows down when collecting starbits. To fix this, right click the game in the main dolphin window and go to 'Properties'. Turn on (tick) 'Alternate Wiimote Timing' and this will mute the wiimote speaker, fixing the starbit slowdown problem. Seems like it might be something to do with the wiimote not having enough bluetooth bandwith to recieve the sounds and transmit controls at the same time.
