Mame XML Rom Set Cleaner is now available 
This application will allow you to create a RomSet corresponding to a custom Mame XML file or created with the Mame XML full Lists Generator application available on this site.
Your RomSet will need to be complete and in Split version for your new RomSet to have all the dependencies associated with Sets (Bios,CHD,Samples,Devices)
I’m waiting for your feedback on the Hyperspin forum:
