Cataloging, renaming, etc. romsets by console

[poodadoo]

I've been collecting ROMsets for a variety of consoles from a variety of places.  I'm fairly sure I have some duplicates spread throughout the variety of sources I've collected from.  Is there an easy way (or even a complicated way) to dedupe my collection, rename them to standardize them, compress them to save space and/or identify games I'm missing?

In ol' MAME days, I'd use something like clrmame but that doesn't work for all the consoles/emulators launchbox supports.

Thoughts?

If you are already familiar with Clrmamepro, then you can use just about any sort of DAT to rename or rebuild your sets.

• No-Intro DATs should cover the majority of the non optical media systems: https://datomatic.no-intro.org/index.php?page=download&s=64
• Redump should handle the majority of optical systems: http://redump.org/downloads/

Without knowing exactly what systems you are trying to cleanup, those two are probably the most common.
