The experiences being reported (as some phenomenological or, if you're an illusionist, "pseudo-phenomenological" thing/property) require an explanation for their appearance as phenomenological or "pseudo-phenomenological". But how do you get from neurons firing in the CNS to such a bizarre, seemingly "unscientific" appearance that is "out there in your face", so to speak?
When you report feeling toothache, for example, you're not just reporting, you're having what appears to be a feeling of being in pain, an intolerable sort of "ringing" that you wish would just end.
Going with another example, when you point your head towards the screen of your computer, you are vividly identifying words on the screen. Or at least you have what appears to be a vivid experience. You're not just "detecting in the dark". It all appears as flashy to you.
How do you explain the seemingness of vividness, the intensity of the feeling, and such?
And, once again, suppose that we manage to find the neural correlates to all of these experiences. We can look at the neural activity and say 'this person is experiencing a vivid experience of red'. And, suppose we can do this across the board, for all experiences. Clearly we are quire far from this. But suppose we can. is that not sufficient to explain consciousness? We have the correlates and we know how those correlate to experiences (qualia, if you will). What else is required?
In your example, the explanation would be that certain neurons are firing in a particular pattern that corresponds to having a certain experience. That *is* the explanation.
You still need to bridge the gap between the physiological and the phenomenological. Chalmers is very clear on what the hard problem is. Even if you have all the necessary correlates, you still need to explain how those translate to experiences/qualia exactly.
And again, if you're an illusionist (I'm still not sure if you are or not), then you still have a hard problem to deal with. How is the seemingness of phenomenological experience coming about? Keith Frankish refers to it as the illusion problem (and he doesn't think that's a hard problem anymore), but I think it's still one and the same thing.

I think this is a misunderstanding of how hings are explained in science. We cannot observe 'causes'. We can only observe correlations. The causal component is always in the theory. it is a construct, not a basic observation. And what constitutes a 'cause' depends on the theory.
So, when we say that charged particles cause electric fields, ALL we have is the correlation between charged particles and electric fields and a theory that describes how the two are correlated. The same is true for mass and gravity. The theory says that one causes the other, but that is a postulate of the theory, not some detailed mechanism.
Once we have underlying theories, we can 'explain' other things via causality, but when we do so we rely on that underlying theory.
So, we can explain chemical bonding in terms of 'electron sharing', more specifically in terms of the formation of molecular orbitals, but such an explanation relies on the deeper theory of quantum mechanics. We can explain how motors work, but only once we have the underlying theory of electromagnetism.
So, what I think will eventually happen is that we will have neural correlates to conscious experiences to the point that we could 'read minds' by looking at neural behavior. We could then point to specific neural activity and say that is the neural signature of the experience. This can even be tested by having subjects report their experiences.
And, my point is that this would be a perfectly good 'explanation' of conscious experiences in terms of neural behavior in the same way that we can say that the electrons in s system are an explanation for the electric fields observed. No deeper 'explanation' is required past the consistent correlation. What is required is exactly the 'translation table' between neural activity and conscious experience.
In other words, there is *only* a soft problem of consciousness, just like there is only a soft problem of electric fields or of gravity.
All I'm seeing here is that you're not concerned with the hard problem. But this does not mean therefore there is no hard problem.
In your physics/chemistry examples, correct me if I'm mistaken, but you're still able to explain how particles cause fields and such (it's just you need to accept the underlying theory first)? That's the thing though. When it comes to consciousness, whatever underlying theory we want to consider, how could that theory explain how neuron firings translate to qualia (or appearance of it)?
ETA: If you think a complete correlation map is sufficient to explain how X causes Y, then that's not a sufficient account. An explanation of causality would still be required, whether talking consciousness or not.
