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. | ||
==From 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: | |||
scummvm > file.txt | scummvm > file.txt | ||
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. | |||
==Manually== | |||
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. | |||
Each engine in ScummVM uses a different number of bytes to calculate their MD5 checksums. | Each engine in ScummVM uses a different number of bytes to calculate their MD5 checksums. | ||

===Under *nix (including Mac OSX)=== | |||
head -c size file | md5sum | head -c size file | md5sum | ||
Where <code>size</code> depends on the engine, as described above. | |||
and run it like this: | |||
===Under Windows=== | |||
Download [http://md5deep.sourceforge.net/ md5deep] and run it like this: | |||
md5deep -p size file | find /i "offset 0-" | md5deep -p size file | find /i "offset 0-" | ||

Alternatively, you can download the [http://gnuwin32.sourceforge.net/packages/coreutils.htm gnuwin32 coreutils] and run the *nix command above. You will need <code>head.exe</code>, <code>md5sum.exe</code>, and the two libraries from the dependency package. | |||
==Submitting the MD5 Checksum== | |||
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. | After you get the MD5 sums of the game files, you can report them by using our [https://bugs.scummvm.org bug tracker].
