I'm sorry if this has been asked already but atm I have launchbox set up with all my roms (practically all full sets) but I'm definitely not a completionist and all those 1000's of games I will never even play is really bothering me.. I would go in my roms and copy all the games I want to keep one by one.. And keep only the best version of those games (no need for a SNES/GB/... version of Mortal Kombat II when I have the arcade version) I would then organise everything into genres instead of platforms in Bigbox.. What would be the fastest (easiest) way of shifting through + copying 1000's of roms? Any recommendations?
