Most MD5's in scummvm source code are useless for G-D-P
because they are computed on the first 2kb or 8kb or 1Mb
or something else. The file size next to the MD5 is
well the size of the full thing.

Would
demo_for: [grimfandango-en-data,grimfandango-de-data]
be ok for you ?

Ok, I'll look it up more in detail tomorrow evening.
