This is a version field. Official sw uses func <code>nn::capsrv::GetShimLibraryVersion()</code> to load this from a global var, which is then used with various commands (the input for those cmds must match value 1).
[7.0.0-8.1.0] This is value 1.
Controls which struct version to use for [[#ApplicationAlbumEntry]] / [[#AlbumFileEntry]]. However, the struct size for the newer version is used regardless on [7.0.0+] for the actual cmds.
