This very simple mod automatically charts your surrounding spawn area and increases the game speed to 32x (Alhough in practice, you will probably see about 3x game speed at most).
This is intended for fast map fishing; disabling the mod once you have the map data you've been searching for is recommended.
NOTE: Once you have a map you like, do the following to get your game speed back to normal.
1. Save the game.
2. Exit to main menu.
3. In the load game screen, press the "Map Exchange String" button, then the "Copy" button.
4. Disable or uninstall AutoChart in the mods screen.
5. Start a new game, and paste into the Map Exchange String text box.
You can also press CTRL + F10 (can be changed in options) to reset game speed to normal if the mod is active.
This mod is somewhat obsolete with the new "Generate Preview" function built in, but will remain here for those circumstances where you may wish to preview maps 'in person'.
