Updating MAME Rom Set?

[Drybonz]

Will the MAME rom set importer avoid importing duplicates when a set update is released?  I want to only get the new and changed roms, but the last step of the import lists all the roms in the set, making me think it's going to allow duplicates.

It should only import duplicates if you enable the box to force importing of duplicates.

The regular import dialog has that option... I'm not seeing it on the full MAME set importer.

Then it shouldn't do any duplicates, it should only add anything newly added to the set or changed status according to the filters selected.

Ok, thanks for the answer.  In the last page of the MAME importer, it lists all the roms.  On the normal importer, it doesn't list the ones it isn't going to import... so I was afraid of messing up my arcade platform.
