> With computation as we know it. Hence my next point , where I'm looking for more detail about how the host universe actually supports and runs the simulation

  You don't really need more detail. Just consider (hypothetically, if you wish) one of our own simulations. Were there conscious, reasoning agents within it, who developed access to computation, the resources that they would have to create their own simulations would necessarily be limited by the scale and scope of the simulation we created. It would be almost inconceivable to most of them that it could be possible to "simulate" their entire world, given their understanding of physics and computation within the bounds we set up. Then there's the matter of time. It doesn't matter very much in a discrete universe whether or not time runs "fast" or "slow" ... each discrete state is the same either way (because there is no "in between"). Just as right now it would task vast computational resources for us to simulate anything remotely like the universe we seem to live in, and it would likely not run "real time", nothing inside the simulation would be aware of the computational costs and duration in our world.
