Pleased to see there's still interest in one of the all time greats.
There has never been the offering of all three battleships, though it was always a promise that never fully realized before the plug was finally pulled. There were just the two, The Hood and a German or Japanese boat, if memory serves. Perhaps East, may, if he wishes to comment on that.
But to answer your question, don't know if it was considered a savegame as such, but what you are referring to is a file named
SleepyD, And yes, it exist. As well as
Creating Custom Campaings and Patrols by
Jackson Clouse.
And I'd be more than willing to share these treasures which are presently stored on a lock-proof fire-resistant medium where they have remained for the last ten years or so. lf the devs/mods give a nod I will provide them to the community. I hesitate not to be coy but not knowing Subsim policy on "savegames" which some boards take as not quite sporting.
And I'd have to have Neal's approval to release the Jackson Clouse material--
as well as any Russian-hacked emails related to Hotel Davolta
