From the Mame32 support.htm....
Mame is a documentation project, sometimes old rom sets are found to
be missing previously miss-dumped or damaged roms, and those will be
replaced as found. Small color proms are also still trickling in. As
new versions of Mame come on board the developers add support for new
iterations and often add these files for missing games [or they will
delete redundant files], this necessitates using that new updated set.
