Multithreaded

[LunaMoo]

If setting in ppsspp is grayed out, it simply means it cannot be activated at the time or require different setting to be activated first. In case of multithreading you simply have to close the game you're running, basically enter settings menu without emulating any game to be able to change it.
Why the bother? Because it wouldn't really work anyway without restarting emulation while many confused users could think it does.
