So I am a novice Mameui user looking for a way to keep updated and it was recommended to me that I try this. I used the guide at mameworld and I am still lost.

What I basically have is a clean version of CLRMame and a mess of Mame versions. I am looking to get everything clean with version 127. My Roms are all mixed up, some updates that I download are unzipped so I basically keep putting them in the Roms directory.

I found dats here: http://www.logiqx.com/Dats/
and here: http://mameui.classicgaming.gamespy.com/

The first site had a superset version of 127 and a regualr one but I really couldnt tell the difference by the desciption.

The official site has a link to a zip file containing 2 dats, one for icons and one for snaps. So for the profile section of the tutorial which dat am I starting out with?

Are there dat files for each artwork folder that I need to grab? Basically once I load a dat I am lost, the settings tab has all sorts of options and the faq lacks detail for a sorry noob like me.
