Here I have a full set of vertical configs for my mame setup running through retroarch using the MAME 2010 & FBNeo cores.  I'm using matsus-4k-bezels retroarch bezel pack, along with the Duimon-Bezel-Project linked there, that uses the amazing reflection shaders with a bezel as a background image.  I went through and manually rotated the screen in retroarch and then saved game overrides for each game that needed to be rotated.

First off, all vertical roms need to be copied over to their own folder.  Included is a powershell script (rom_copy.ps1) that will use the vertical.txt from the same folder and copy those files to "roms_vert".  You will have to open that script file in a text editor and replace the $sourceFolder, $destinationFolder, and $filenameListPath with your own directory locations.  Then that script will look for "vertical.txt" in the directory specified, I chose to already put it in a "roms_vert" folder, and copy over the files that match that list, into the "roms_vert" folder.  That will leave those same files in your initial roms directory, as I did not want to delete them initially because I didn't know how things were going to go.  But i provided another script that should go back and delete those original copies if needed.

So in LB I bulk changed rom path to the "roms_vert" directory, and then in I loaded the MAME 2010 core in retroarch, launched a vertical game from that directory, set Video->Output->Video Rotation to 270 deg, then saved that as a Content Directory Override.  That took care of a vast majority of the rotation needs of the games.  So the remaining games either needed to be set to 90 deg, or 180 deg, and saved as a Game Override.  So, in theory, once you do that process, launching from your "roms_vert" folder, and set the Content Directory override, all the other per-game configs that are in the MAME 2010 config folder i provided, should fill in the gaps of all the games that aren't the base 270 deg Content Directory Override.

I also used the FBNeo core for 102 games out of my setup.  I copied those over into the MAME 2010 configs as well, in case people didn't need to use FBNeo for anything, like I had to.  Those I manually edited per-game to add the "Use Custom Command-line Parameters" area of the Edit->Edit Metadata/Media->Emulation window.  Found the correct format to launch a different core somewhere on the forums (thank you to whoever posted that).  It is "-fullscreen -L "cores\fbneo_libretro.dll" for my application.  Just F.Y.I.

I think that should cover it.  Hopefully it can help someone who is working on their Arcade setup using Retroarch.
