There is nothing wrong with the samples.
The provided samples datfile which I provide is for MAME .117 (not u1 or u2). There are a couple of nodump sets (e.g. 005) which are known and marked as nodumps. Easy as that. The samples are taken from the official MAME sample page. There are some corrections related to sample parent/clone relationsships done (e.g. MAME devs kept invaders as a sample parent for various sets while sample support for that parent was completely removed. Consequence is, the clones are corrected to use their own set.
