Hello all, I just thought I'd make a quick post clarifying that SF1's saves are now stored under the path
C:\Program Files (x86)\GOG Galaxy\Games\Starflight\cloud_saves\STARFLT\PLAY
NOT
C:\Program Files (x86)\GOG Galaxy\Games\Starflight\STARFLT\PLAY

It took me a bit to figure this out, but the old method of backing up and restoring saves works fine, so long as you're operating in the correct directory.

Have a fine day, folks :)
