I've spent some time with RomLister today - removing nudie games / mahjong etc 
Along with this I want to remove clones as they will clutter up my Hyperspin list...
The issue I have is, selecting No Clones works great in 80% of cases, but in some, the root is the Japan version, but being an english speaker, I want the US/World/Euro version instead...
Is there any tool or easy way to exclude clones, but default to the US English version?
