Argh! Previous post was trashed! Please ignore it.

MAME currently supports putting all CHD's in one directory - e.g. mame_dir\chd. You only need to create the folder and add it to the rompath line in the mame.ini. You don't actually have to have folders organised as rom_dir\game_dir\chd_image_name.chd anymore. This was recently discussed on the Official MAME bulletin board http://www.mame.net/cgi-bin/wwwthreads/showpost.pl?Board=mamegeneral&Number=130304&page=1&view=expanded&mode=threaded&sb=7#Post130304

Currently ClrMamePro does not support this feature. Is there any possibility of supporting this organisation of chd's in a future version of ClrMamePro?

Cheers,
