Oh, I never get aware of the drag and drop feature, ok that was I did.

I have a dir named ROMS067, wich have all roms of mame 0.67 cleaned and working, and in another dir I named ROMS068 y have all new roms of version 0.68 (new and changed roms), so I did things like you told me: first I downloaded mame 0.68, created a dat file and did a scan with all checks and fixes to the dir ROMS067.
I got a list with the missing sets and files, then I draged all the files on dir ROMS068 to the result scan window and clrmame started to rebuild the roms (before, I set the source and destination path on the rebuilder to the same location (ROMS067)), after a while clrmame did a fast scan and I got all roms perfectly rebuilded on dir ROMS067 with no missing sets or files.

I'm very pleased with that, since I didn't had to do anything more, I was just a charm.

Very thanks to you roman, now my task to update roms will be more quickly.

Thanks again.
