Hi Roman

One idea :
Update a datfile via the right click in the profiler.

A new entry in the right click menu of profiler like 'update the datfile via wwwmode' would look in the whole website adresse memorised in wwwmode.
If there's a datfile update, clrmamepro ask to confirm update.
If no datfile update existe...
Clrmamepro would do it alone (only the right click...)

Good or bad ?
