Hello I am new to attract mode.
I have set up two screens (I'm just getting warmed up ha ha) - NES and Sega Master System
I have a few questions and would love a little help please

Ok
Q1) In the Settings, Emulator - there is an add an artwork, is this only for specific artwork for themes?
e.g. I notice there is no titlesnap or cartridges folders in the C:\Attract\scraper\NES\.
So would this be a correct use case?
Q2) Also in addition to Q1
On my drives z:/NES/artwork/clearlogo/
This is the name for kodi but marquee for Attract.
In the same Add Artwork, could I add "marquee" and place z:/NES/artwork/clearlogo/
Would attract automatically use this as marquee artwork (the filenames are identical)
If I were then to Scrape, would the files on the z drive be overwritten when I scrape the media?
Would any missing be added to this folder when I scrape?
Or do these directories just get copied when I scrape into the C Drive and the final C Drive content ignores thegamesdb where there are z drive marquees?
Q3) I tried the display cool, but I could not get videos to work. I tried changing my config file.
Please see:

artwork wheel $HOME/Sega Master System/wheel
I have saved a video in c:\Attract\scraper\Sega Master System\videos\Alex Kidd in Miracle World (USA, Europe).mp4
In the Display "Cool" I have the background to "video"
I did try adding a videos line, I also tried changing the artwork videos to artwork video, but no joy... What am I doing wrong?
Question 4) I have been through the menus (I assume themes can be installed to increase the displays). However I was looking for one I saw on line. The best way I can describe it, was an arcade cabinet to the left, it was playing the video. On the right it had a disc spinner / logo wheel - forgive the terminology but could you point me in the direction to make that happen? Or give a hint

Thanks for your help, getting me started
