While you can attempt to Save a State for any game in MAME, there is no flag in the source saying that this particular driver has had officially coded support, so any success you have using the SHIFT+F7/F7 is purely coincidental. It may work one version and not another. If the driver/set were to have a GAME_SAVE_SUPPORTED flag in the source, perhaps there would be something that could be done about it. Those with that flag are games which have had the Save State routine EXPLICITLY CODED for the driver/set. Using the command -autosave will tell you if a driver/set supports Save States. From the config.txt document in the DOCS folder: F7 Load a save state. You will be requested to press a key to determine which save state you wish to load. Note that the save state feature is not supported for a large number of drivers. If support is not enabled for a given driver, you will receive a warning when attempting to save or load. Again, this is not a bug and closed because a driver/set which does not have Save State support coded is not guaranteed to successfully work with saving or loading of States. Sorry.

          state feature is not supported for a large number of drivers. If
          support is not enabled for a given driver, you will receive a
