there is a long way to get there.
1) use cmpro to create a datfile from you unsorted folder
2) use listtool or datutil to convert it from cmpro to romcenter format
3) use a text editor to replace "," with "-"
4) use a text editor to replace "¬" with ","
5) use a spreadsheet to import the comma separated file
6) use a spreadsheet to eliminate lines with duplicate crc
7) save it back to comma separated file
8) use text editor to replace "," with "¬"
9) use clrmame to import this file and check your collection.

Maybe there are better solution, this is what I'm doing anyway.
