Thanks for this. It behaves for me the same as the previously installed package, except that the files show now the same date. An exception is dosbox.conf, which is correctly edited by the installation. I've tested eng and deu languages. Both work, including their installations.
I see that you've removed eng\COPYING.LIB and eng\INSTALL. Both were present before, but not marked with the obsolete EA nor removed. Strange, but minor and not worse to change anything.
