The point is that only a tiny fraction of all SCUMM games have a
detect file which is bigger than 64kb.
Basically, on those games which have a single "big" data files (i.e.
certain Mac versions of LEC games, and possibly NES/C64/etc. dumps --
not sure about HE games) would require computation of new MD5
checksums if we go for 128 kb. With 64kb, I think only COMI would be
added to that list. With 32kb, there'd be some HE titles on the list,
too.
