      A notable annoyance with some of the more obscure formats (eg Texas Ti99, Intellivision, Apple II) is that they display in a stretched format rather than the proper 4:3 aspect ratios they ran it back in their day.

      (For example Jzintv displays a screen 18 inches by 12 inches on my monitor, when it should properly be 16x12.)

      I've tried every display option in the Runcommand menu to fix this, but I can only make it worse, not better. (I currently get side borders, just not big enough ones. All the other resolution settings just lose the borders and stretch the picture all the way to the edges.)

      Is there anything that can be done here? Linapple, for example, has internal menus, but nothing that changes the aspect ratio.

          @superfella there's no catch-all method for standalone emulators, since by defintiion they are all bespokely configured. however i would expect that by default most emulators should use the correct aspect ratio for their emulated system when using default settings.

          (For example Jzintv displays a screen 18 inches by 12 inches on my monitor, when it should properly be 16x12.)

          i suspect this is because your monitor does not have square pixels, or is misconfigured. what's the native panel resolution? what's the physical dimensions of the monitor? what is the display mode set in /boot/config.txt? what is the display mode set in runcommand?

            @dankcushions As I said, I've been through every resolution option in Runcommand. It's a bog-standard 24"16:9 monitor.

              @superfella still, that's the information I would need to diagnose. take it or leave it...
