Update 06/23/2022 So I continued to run the metadata updater it eventually began to install the bezel projec.t I think its a priority issue with you media request. I had to run it a few times to get box art and marquees. Then it eventually got the bezels. I recall previous version i would select that and walk away as it took to infinity to get all the data on one request. Might be a bug with the release.
That's exactly why I am here. I have ran the update metadata a few times and no bezels in Mame .239 > IM on a fresh install and wanted mame and majority everything else in retroarch. Did not want to go further until i figure why mame bezels are populating/installing.
Update looks like the issue might be with the emumovies sign in plugin. As mentioned fresh install so its grabbing artwork. box, marquee etc. I'm guessing bezel are not a top priority. Keep running the download metadata. But each time or ever other time I have to sign into emumovies repeatedly each attempt. I was on 12.2 or something prior to update and didnt have to sign in emu movies but once.
