Difference between revisions of "Reporting unknown MD5 checksums"

This page contains instructions on what to do if you got a version of a game that the ScummVM team is not aware of (perhaps a rare version, or a less known one, or perhaps an unknown non-English version). In such cases, here's what you can do to get your version supported under ScummVM:

* The easiest way would be to check the ScummVM console window, which will report the unknown MD5s you got. If you can't see the console window, you can redirect ScummVM's output to a text file, by running ScummVM as follows:

* If for some reason you can not see ScummVM's window or do not get any output in the text file, you need to follow an a bit harder process. The MD5-based detection in ScummVM uses the first bytes of each file to determine its MD5 checksum. This is necessary to speed up the detection process and to avoid having to calculate the MD5 checksums of large files, which would make game detection very slow.

To get the correct MD5 checksum, run the following:

'''Under *nix (including Mac OSX):'''

'''Under Windows''', download [http://md5deep.sourceforge.net/ md5deep]

and run it like this:

Where ''size'' depends on the engine, as described above.

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.
