run retropie-setup, update your script. then run the configuration editor – see https://github.com/retropie/retropie-setup/wiki/Configuration-Editor

the wiki is a bit out of date here, but you want

1 Configure basic libretro emulator options
14 Configure additional options for mame-libretro
1 Aspect Ratio
20 Square

this basically makes all libretro mame games display at 1:1 ‘PAR’ resolution (ie, every pixel is treated as a square), which fixes your issue with vertical games. I think this should probably be the default for mame libretro, but really we should fix the core so it renders these games properly…
