I've noticed that ClrMame Pro preserves attributes from the source sets during rebuilds. i.e. the archive, hidden, read only and system flags.

As a general rule I suppose this is the safest approach to take. However, I would like to see an option to set those flags to a default value. After all, with roms they don't ever have to be system or hidden or anything anyway.

I know it sounds a bit pedantic but I believe it is no more esoteric than the time stamping options currently in the system and would help produce cleaner, more consistent romsets.

The reason I ask is that I find myself spending some time cleaning dodgey attrib options out of my romsets. The 3 most common options I see in roms are 'nothing', +a or +r.

Cheers,
Tim
