I downloaded Retroarch today but I can only run it when going into the unzipped file itself in stead on clicking onto an Icon on the screen, am I missing something to do because the aforementioned process seems very inconvenient
RetroArch doesn’t take over file associations, and that’s on purpose. It supports dozens of file extensions, including common multipurpose ones like ‘bin’ and ‘iso’, and it would be awful if it decided that it owned all of them.
