What version is retropie supposed to be using? From there I could verify that the files are correctly named based on hashes of the internal files then go through the renaming to get them to 1.47 for mamedb data and to 1.57 for the history.

RetroPie’s (v2.4x beta, not sure about earlier versions) default MAME emulator is MAME4ALL, which is a fork from MAME v0.37beta5. Which is [b]old[/b] :) Like circa 2000 old.

Not sure why this is where the magical spot they forked from, but in general the older version performs better on the Pi.
