	)

netplay_resolve_input : pointer to netplay object : frame pointer for which to resolve input : are we resimulating, or simulating this frame for the first time?

"Simulate" input by assuming it hasn't changed since the last read input. Returns true if the resolved input changed from the last time it was resolved.
