man dolphin-emu

[Shonumi]

Maybe it's just my years of experience programming, but I don't see how that's easier than typing this in right place in the source code:

Code:

exit(); //yup, that's it, a one-liner :p

But whatever floats you boat

Also, I probably should have checked this earlier, but this is even easier. Dolphin has a hotkey for exiting. Stopping emulation is set to Escape, but you can change that:
