I picked up the SimCity Box expansion set, and it came with a few extra disks. I suspect GoG has patched the original SimCity to not need a cd, but I am not sure of all the changes. Since the core game is patched, does that cover the expansions?

The set I have includes SimTower, Streets of SimCity, SimCopter, SimCity Societies Destinations, Sims Carnival SnapCity,

I know some are for SimCity 4, and others for SimCitty 2000. There seem to be a few more expansions to pick up, as my box is missing two.
Less that it was patched to not need a CD, more clever trickery to mount the directory as a CD itself.
