Super Mario Galaxy

Super Mario Galaxy is a 3D platform game developed and published by Nintendo for the Wii. It is the third 3D platformer in the Mario series, after Super Mario 64 and Super Mario Sunshine. A sequel, Super Mario Galaxy 2, was released in 2010. The game follows the protagonist, Mario, on a quest to rescue Princess Peach from the game's primary antagonist, Bowser. Levels are galaxies filled with minor planets and worlds, while gameplay is updated with gravity effects and new power-ups. Super Mario Galaxy was first shown at E3 2006 and enjoyed a high level of pre-release awareness. The game has been hailed by several gaming websites as one of the best video games of all time.

Music
Music stops after a few minutes when not using the LLE plug-in. A patch discussed on the forums extends play for longer, but doesn't fully correct the issue.

Dolphin Hangs Before Credits
Dolphin will hang before the end credits play, refer. It is related to the HLE sound plugin. To see the credits and save at the end without hanging, use LLE or disable sound. Using Save States may cause the credits to not play despite those fixes.

Inverted Reflections
Certain materials that reflect Mario have inverted reflections, refer. This issue actually also exists on real hardware, so it's not an emulator bug.

Poor Performance With LLE Audio
When there are a lot of audio effects happening concurrently the framerate tends to dip which causes distortion in the audio. If you set your audio backend to OpenAL and increase the framebuffer to anywhere between 1-5 then the audio will be less likely to distort when your framerate drops. It does not prevent framerate dips but it does combat audio crackling when the framerate does dip.
