Tips or Tools to sort a set ?

[MAntoine]

Hello,

I want to have some tips/tools to sort my roms.

I give an example to explain:
I have a Full Set for a console => Check Ok in RomCenter or Romulus

Now I want to avoid the multiples duplicates BUT with keeping some single version.

Ex:
Game A in Japan
Game A in US
Game A in US (Beta)

Game B in Japan

Game C in US (Beta)

=> I want to have
Game A in US
Game B in Japan
Game C in US (Beta)

Because Game B and Game C are in single version.

I cannot exclude ALL Japan version and ALL Beta version automatically (like in Skraper with extension files)

Thanks
