In 3.117 you have this option but now without enabling datfiles errors options clrmame choose force merge/split? (i suppose because freeeze2/3/4 now all wrong with many crc error).
If i enable datfiles error reporting clrmame let me choose if i want remove relationship.

Can you re-enable previus version behaviour and without ask remove "parent" relationship, or put this options in another position?
