Does SID initialize all its components ?

What kind of initialization did you expect? I believe
most SID components aim to start up in a state similar
to powerup of the physical devices. However, since some
features of the hardware may not be emulated, and others
may be hidden by properties of the host I/O, you may get
away with using initial state on the simulator.
This is true in general with simulators: it is possible
to get a "false positive" in the sense that a program
may run on the sim but not on hardware.

Not really. What you're seeing is probably a coincidence.
