I think al this can be solved in principle. The question is only
how much time it requires. I think that all intelligent sentient
beings can be detected in principle. Of course I can't prove that.
This would equal creating a formal definition of sentience, which
nobody has been able to do yet.
You could for example record al the intermediate states of the
simulation. (When the simulation is deterministic you wouldn't
even have to do that. You would only have to remember the
beginning state of the simulation and its total duration.)
Then afterwards, the creator could in principle examine the
simulation in detail. Dependable on the complexity of the
sentient beings he wants to detect this examination could
take a time extremely much longer than the duration of the
simulation itself. The question is only, does it take longer
than time the creator will exist.
I expect it will not be that difficult for the creator to
detect sentient lifeforms in simulations. For example it
is also not so difficult for humans to detect selfreplicating
systems and moving systems in the "game of life". Of course
these current universes are much to small to create sentient
or even intelligent beings.

But you could learn...

Systems in "game of life" worlds can alter their surroundings.
When they do this in an indirect way, this could be considered
using tools. I don't see why tools can't also exist in "game of life"
worlds.

I didn't assume it should be very easy. But it shouldn't be to hard
to communicate with other intelligent sentient beings. We will have
enough in common. It should be just as hard as communicating with
any other intelligent sentient lifeform.

Interesting, where can I find more about these Tierrans?

The idea was they would be resurrected together with other
individuals form their world. And why should the resurrection
world be made a weird caricature of their real world. It could
just as well be made as familiar as possible to their real world.
This whole issue reminds me a bit of the Riverworld saga by
Philip Jose Farmer. Here all the people who have once lived
on Earth are resurrected on another planet along the banks
of an extremely long river. The river is spiraling the whole
surface of the planet and the river valleys are separated
by insurmountable mountains. The people are restored with full
health in 25 year old bodies. When killed they will
immediately be resurrected at another location. I enjoyed these
books very much. :->
