The developers simply cut out the feature rather than replacing it.
In SR3 the buttons are missing, SR4 crashes if one tries to access the features (lousy port, really ... shame on you, voliton/deep silver/whoever).
The GOG versions have zero to do with the developer or publisher, other than being given the game files. GOG does whatever they want with it with no input from us.
