It's a very hypothetical scenario, so being not sure is, surely, the correct response. But I revert to pondering what I might do if in real life it looks like conscious states are computational macrostates. I would have to go on trying to find a perspective on physics whereby such states exist objectively and have causal power, and in which they could somehow look like or be identified with subjective experience. Insofar as my emulation concerned itself with the problem of consciousness, it might do that.
