Looks like the locations where the Selph scraper gets data is incompatible with Emulation Station. In particular progettoemma has video snaps recorded with a codec that almost no device supports. They won't display video in OMX or a PC running windows 10 unless you search around and add a codec pack that happens to have predictive 4:4:4 (I used the free K-Lite 1400 Full). And the text descriptions input in to the gameslist.xml file has tab characters or something embedded in then. I used Notepad++ and made all special characters visible and didn't see anything other than the offending lines indented and showed tab lines. I had to delete them all. Also, the descriptions are rife with escape codes for carriage returns and line feeds ( 
) . I just got rid of all special characters and other than the ones for quotes or apostrophes and then manually adjusted each paragraph by hitting enter twice to add my own line feeds where I wanted a new paragraph and cleaned it all up. I then used Handbrake to batch re-encode all of the scraped snaps to the "normal" or "High Profile" preset and turning down quality to 25 to make the files a little smaller (on par with the original sizes).
