First off, thanks for the folks who run RetroRoms!
Apologies if this is available somewhere on the forums, I've been searching for hours with no luck. What's the difference between the chds and the chds_temp folders in the BDA under MAME?
As a side-note the forum search takes me to the https://www.retroroms.info/forum/?action=goto&search=1 page and I simply get an access denied on that page. I'm a premium member. This made trying to find info about chds_temp quite difficult too :-(.
