. To quote myself:

* We can check for corrupt files (this requires MD5 of all files, and 
is not something I am aiming for currently, but might be interesting in 
the future, e.g. for doing a 'scummvm -check TARGET' command)

This was just an example of a hypothetical, optional future feature :-)

OK. Which is the first indication that taking just the checksum of the 
first file is not always enough. However, at least in this case I see 
no problem arising from this (distinguishing languages is mostly 
important for the V1/V2 games, so that we can select the proper font).
