This set of Python scripts will extract information from a T4C installation directory.
Currently, mainly "rtmaps" are really supported (the small radar maps at the bottom of the screen). They will be extracted as bitmaps in the output directory. The sprites IDs are also extracted to JSON and saved in the output directory. May add sprite bitmaps and maps in the future.
