Game Name? Metroid Prime 2: Echoes
Game ID? G2ME01
What's the problem? Describe what went wrong in few words.
Using any version starting from 6024 will cause the sky in the game to be completely black. It literally has no sky when you are in an outside place within the game. The versions before it look completely normal in the game.
What did you expect to happen instead?
I expected there to be a regular sky when I look up and around.
What steps will reproduce the problem?
[Don't assume we have ever played the game and know any level names. Be as
specific as possible.]
1. Start Metroid Prime 2 in Dolphin 6192 to see what the sky should look like.
2. Start Metroid Prime 2 in Dolphin 6204 to see the black sky that shouldn't be there.
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?
Many versions between the current latest 6266 and a really old version 6051 i think to bisect and find that 6204 was the build that broke the sky.
Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
From my testing anything including 6192 and before works as it should.
What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Windows 8.1, i5 4690k, MSI R9 280.
Is there any other relevant information? (e.g. logs, screenshots,

In Prime 2/3 the skybox is drawn by setting the depth range to 1.0 - 1.0, drawing the sky, changing it to something lower and then drawing the rest of the world. In Prime 1 they use a range of 0.99900001 - 1.0, which is probably why there's no issue in that game.
