I believe it is not correct. You can put new features that do not exist in the physical world in a simulation. For example, you can double the number of quarks

I believe it is not correct. You can put new features that do not exist in the physical world in a simulation. For example, you can double the number of quarks in a proton as long as you define a mathematically consistent interaction to allow so. Then you created a richer simulated world.
