Wait, what was your question? You didn't ask about anything in particular.
If you're asking how well your laptop will play Dolphin, the answer is that it won't do very well with your specs. 1.6GHz is way too low to get decent speeds. Not sure if your GPU will handle 1x internal resolution all that well either (disclosure: I dunno too much about mobile GPUs).
If you're asking someone to recommend you a Dolphin build, you could try something really old. It might run better, but it would be a lot buggier than current revisions.
