The platform name is correct, so scraping should get some results when using ScreenScraper as the source. If you don't, then add more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first, and specify which games you tried scraping.
I also noticed there's no gamelist file in the rom folder. I would think scraping would have created one?
The gamelist is created by EmulationStation regardless of any scraping operation. By default is not in the roms' folder.
