Import USA arcade/mame rom clones over originals

[GiSWiG]

I don't want to import clones unless it is the US variant. Then, I want the US variant over the original. When importing roms, there doesn't seem to be a way to import the clone over the original even though I specify to prioritize North America. Is this something I have to do manually?

For example, 1944.zip is imported but not 1944u.zip which is the USA clone. I think most, if not all, USA variant end in U so I'm thinking of exporting the set, replace roms with its USA variant and then import that set, keeping all clones. 

So unless there is another way I would, import the set (FBNoe, mame2003, etc) skip clones and prioritize by North America, export that and then replace any roms with its USA variant which hopefully is any clone ending in U and then import that set importing all clones. I am using full-non-merged roms too so no issue with copy/replace.

I mostly use FinalBurn Neo and MAME 2003-Plus for Retroarch but same idea applies to any MAME variant.

Hi @GiSWiG.

From what I've just tested, it does appear that if you use the fullset MAME importer, then the region priorities do take properly (I see 1944u as the main game), while if you are importing via ROM importer and using MAME metadata, I'm seeing what you are seeing.

Will mark it down to investigate further to see if there's something that can be adjusted here.
