Here is a patch against the versioning branch that adds support for reading the new format by just adding the new version number. It also reads and writes the directPlay GUID (stored in GameSettings - I know it's not in the dialog, but the object already holds the gameId and this is similar information).

Thank you, but I did it a slightly different way which was much more comprehensive.
