Emulator

Game Name?
Super Mario Galaxy

Game ID?
RMGP01

What's the problem? Describe what went wrong in few words.
When the game asks for you to "point/tilt your wiimote at the screen" whatever controls you added to the EMULATED wiimote, nothing happens. You remain forever in the galaxy, and no matter which key you press, nothing will happen. The specific galaxy is the one where you must surf on a ray and the other where you must roll a star ball.

Also if you try to shake the wiimote the key-pressing will be rarely registered and even if it in fact becomes registered, there will be a delay before something ever happens.

What did you expect to happen instead?
Have proper movement and key-pressing to be registered.

What steps will reproduce the problem?

1. Start the game.
2. Enter one of the first 2 domes (depends on the galaxy listed above that you want to test).
3. Reach the "npc"s and talk to them. This will trigger a scene where you must hold/point/tilt your wiimote to achieve the so-called "basic" position, which seems impossible to me (and others who have experienced this issue).

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?
Dolphin 4.0-3935 (current master)

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Probably, yes. Will try to track it.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
OS: Windows 7 Ultimate
CPU: Intel(R) Pentium(R) CPU G620 @ 2.60GHz
GPU: AMD Radeon R7 200 Series

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