HTGDB Missing

Hey all.  In search of a bit of help finishing off the HTGDB sets (using DatVault for the dats).  Mostly looking for a few cue files, can't find the right MegaAGS for the MiSTer set, and also just can't seem to find the right MD+ files that it's looking for.  I think I've hit my limit on searching archive.org, so turning to the experts for help... fixdats attached, any help appreciated.
