first, thank you for the reply. the chd lister will be great to have! thanks for the explanations. i'm getting right now 0.173 of all the roms and chds. i decided this will be a better route because that way i can update my set on a regular basis. if i'll remove stuff out of it it will be harder i guess, which means that i better just filter the games i want to play.

so basically i need to get clrmame as you said, use the merger as "non-merged sets", and then use the scanner as split sets? i just miss on the final bit of info - once i finish with scanner, how do i preserve only usa rom > europe > world > asia\japan etc? on another note, is there any way to discover the roms in my list which require a chd to run, but don't have it?

thank you for a great tool! i just had my rom list reduced for ~10k to around 2800 games like nothing. i wonder though, all my games are in 7z format. is there any way to extract all of the games from the 7z into separate dirs and somehow process the entire folder with the subdirs to leave only 1 version of each game? for example, if usa version exists i'd prefer usa. afterwards i prefer world, then europe and only then japan\asia when others are not avail? i just think it's better to have mame games extracted, as these often aren't small files like old console roms.
