Detailed Description

Definition in file gfxinit.cpp.


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.

static void DeterminePalette (  )  [static]

Determine the palette that has to be used.

  • forced DOS palette via command line -> leave it that way
  • all Windows files present -> Windows palette
  • all DOS files present -> DOS palette
  • no Windows files present and any DOS file present -> DOS palette
  • otherwise -> Windows palette

Calculate and check the MD5 hash of the supplied filename.

Parameters:
file filename and expected MD5 hash for the given filename.
Returns:
true if the checksum is correct.
