No, it's a setting in the .VMI file. (offset $64) It uses two bits,
bit zero indicates whether the file is protected, bit one indicates
whether it's a game or data, so the possible values are:

%00 = 0 = copyable, data
%01 = 1 = protected data
%10 = 2 = copyable game
%11 = 3 = protected game

The VMU tool can (currently) only handle values of 0 and 3, but you
actually want a value of 2

You can change this easily by opening your .vmi file in a hex editor
