## Function Documentation

void CheckExternalFiles | ( |  | ) |

Checks whether the MD5 checksums of the files are correct.

Note:
  Also checks sample.cat and other required non-NewGRF GRFs for corruption.

void UpdateNewGRFConfigPalette | ( |  | ) |

Update the palettes of the graphics from the config file.

This is needed because the config file gets read and parsed before the palette is chosen (one can configure the base graphics set governing the palette in the config after all). As a result of this we update the settings from the config once we have determined the palette.
