So LaunchBox has recently taken to displaying "Downloading Missing Retroarch Cores" and taking forever to complete a single drag n drop import of a title. I'm not sure when this behavior started - probably a few releases back; I haven't imported any titles in a while, but each game I import takes 3 minutes of waiting while LaunchBox does god-knows-what in the background, preventing me from importing additional games.
I installed RetroArch a while ago on my F: drive, but moved the folder to my newer, larger hard drive. RetroArch is listed as a plugin, but I don't really remember enabling this.
What am I doing wrong?
