Hey Roman, I just moved my *.chds *out* of their various directories and placed them directly into the \ROMs directory along w/ all the other zips. [easier to carve up 4G chunks for back up purposes]

Now when I do a scan w/ clrmame it's hitting the *.chds and taking *a lot* longer than it did when they were in their sub-directories? Regular zip checking speed is unchanged.

Was the code branch treating them differently if they were stored that way vs in the flat \ROMs directory?
