No hardcoded text exists in the game apart from the version number (v1.21).
The month names are defined in the game.ini of your mod. In fact the whole calendar system is.
The vidcast window title comes from the explore_vidcast line in strings.ini (the race name is inserted at the "%s").
The mission time messages are in mission-specific quests game_pirate and game_brass.
Sorry about the RAM and BOARD labels, those must be five characters long to center properly
Good luck with your project!
