Alternatively, you can download the [http://gnuwin32.sourceforge.net/packages/coreutils.htm gnuwin32 coreutils] and run the *nix command above. You will need head.exe, md5sum.exe and the two libraries from the dependency package. | Alternatively, you can download the [http://gnuwin32.sourceforge.net/packages/coreutils.htm gnuwin32 coreutils] and run the *nix command above.

After you get the MD5 sums of the game files, you can report them by using our [https://bugs.scummvm.org bug tracker]. It is much preferred over a post in the forums. | |||
Also to speedup things, please consider providing directory layout of your game. | |||
