Game Name?
Metroid Prime 2 Echoes/Metroid Prime 3: Corruption

Game ID?
G2ME01/RM3E01

What's the problem? Describe what went wrong in few words.
The games effectively freeze on boot when deterministic dual core is set to "fake-completion". They display only a white dot in the middle of the screen with FPS 4 VPS 60.
Setting deterministic dual core to "auto" or "none" allows the games to boot, but they then suffer the classic "black bar" issue.

What did you expect to happen instead?
I expected the games to boot normally.

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. Open the ISO properties for MP2/MP3
2. Set "deterministic dual core" to "fake-completion"
3. Boot either game

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?
4.0-4161 (works), 4.0-4173 (works), 4.0-4191 (works), 4.0-4197 (works), 4.0-4199 (works), 4.0-4203 (broken), 4.0-4205 (broken), 4.0-4215 (broken), 4.0-4250 (broken)

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Yes; 4.0-4199 and earlier work just fine.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
OS: Windows 8.1 x64
CPU: Intel Core i7-4770k @4.4Ghz
GPU: Nvidia GeForce GTX 970

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

I made sure that no cheats were enabled so I could rule them out as a cause. It appears that 4.0-4203 (the fifo-overflow-fix merger) caused this issue.
