Emulator

Game Name?

Super Mario Galaxy

Game ID?

RMGE01

What's the problem? Describe what went wrong in few words.

Major texture losses on both ground and entities.

What did you expect to happen instead?

I expected the textures of the ground and other things to load correctly. This was clearly not the case.

What steps will reproduce the problem?

1. Start the game. As soon as you start to control Mario you will notice the problem (see screenshots).
2. Use the standard settings, don't change the config at all.

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?

4.0-6796 dev and a couple below.

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

No, this occurred on all older versions I tried to run the game on.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)

Using a Mac Mini 2012 running OS X Yosemite 10.10.3 (14D136). See specs here: https://support.apple.com/kb/SP659?viewlocale=en_US&locale=sv_SE [i5 Version].

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

Yes. See these links of the 3 screenshots I took of the game:

The game is unplayable in this state.
