i want to edit gamelist.xml files myself and add some manuals to Batocera, without scraping these, but i fail to get any info anywhere on the net on how to do this. what do i have to add to <game> </game> to get manuals visible in Batocera ? they are in .pdf and i already have them i dont want to scrape also because i fear things might get overwritten or changed as i have altered most gamelist.xml files.
