> When I try to use clrmame pro, how can I view if a game use any chd file?

Well....generally clrmamepro lists issues in its scanner. So as long as you don't have any issues with chd files, they won't appear. Of course you can see the chd files listed in the 'sets' window...as you can see the full database in there.

Of course you have to enable 'diskimages' in the scanner...but you know that since you have read the documentation, haven't you ;)

Well...where's the problem? Keep one datfile (in this case Logiqx's diff-datfiles would be the best solution) for each version, setup profiles in the profiler for each of these dats. That's basically it. Be sure you got Sets, Roms and Diskimages enabled in the scanner.
