Miscellaneous small text fixes

I don't know if GOG version required "memgame.txt" or not but the game missing this file in "3ddata" folder in GOG version.

I'm not affiliated with the dev/pub or GOG, so the only help I can offer is to suggest you contact GOG Support about it, especially if the missing file prevents the game from running properly or at all.

Has this been resolved?
