You don't need datfiles.

After reading the documentation and following tutorials (e.g. at mameworld.net/easyemu) you can simplify everything to the following simple procedure

1) Profiler->create-> add a profile for your mame executable
2) Settings->rompath/samplepath selector -> setup your rom and samplepaths
3) Scanner-> enable all check and fix options and hit scan.

If MAME gets updated, you replace your MAME executable and clrmamepro will detect the update and automatically gets the updated data.


To add the sets to your collection:

- add an addpath in settings and use scanner's fixmissing option

or:

- use the rebuilder. Rebuilder destination has to point to your rompath, source to your newly not cleaned not added sets. This can also be done by drag&drop from the scanner.
