Ok so i understand how to get rid of clones.
My question is how to get rid of duplicate roms using the filters
An example, my mame rom set has maybe 5 or so different rom revisions for 1943.
Id like for only one to show in my mame rom list.
I'd prefer to use the filters and not delete the roms.
I'd also not want to manually edit my rom list
Any help is appreciated
