      I'm using Retropie 4.4.4
      On the Retropie Github wiki it says that mame2010 now supports roms in 7z archives.
      https://github.com/RetroPie/RetroPie-Setup/wiki/MAME
      I added .7z to the es_systems.cfg file so they show up in the emulationstation mame menu.
      But when I try to run a rom in a 7z it just drops me back to the ES menu
      Could somebody please help me fix this problem?

      I used 7-zip x64 v18.06 on maximum to compress the roms.
      Do I need to use an earlier version of 7zip or less compression for them to work on Mame2010?
      I tried different settings but none of them worked.
      7-zipped roms worked fine with NES, SNES, Megadrive etc.

        @johnsorger6 How did you create the 7z archive ?
        Can you run with verbose logging enabled and post the contents of the log file /dev/shm/runcommand.log on pastebin.com so we can take a look at what errors appear ?
