innoextract 1.6 unpack the installers wrong.
innoextract 1.7 unpack the installers correct, but gdp still doesn't see
data files (i checked with make-template). I think it's because they was
moved: Book 2 and 3 to root directory, Book 1 to "DAT" directory (i
checked them with scummvm. Yes, it's found the games there).
So there is two parts for solution. First: wait until innoextract 1.7
appears in Debian (i made a request:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=902579). Second:
fixing gdp scripts (developer's magic).
