Wait a second, this doesn't make sense. If the universe is timeless, then you don't have to actually simulate the universe on a computer. You can just create a detailed model of the universe, put in the neccesery causality structure, stick it in the RAM, and voila! you have conscious beings living out their lives in a universe. You don't even have to put it in the RAM, you can just write out symbols on a piece of paper! Or can this impeccable line of reasoning be invalidated by experimental evidence?

The process of generating the model requires law-abiding computations.

How do you know that?

All universes with causal structure obey laws that give them that causal structure, you have to check that your model follows those laws, this requires law-abiding computation.
