      Or to be specific, lr-mame2015.

      As I understand it, MESS is incorporated into the later versions of MAME, which I presume includes lr-mame2015. My question is, how do I run a non-arcade game with it, assuming that's actually possible?

      The default EMULATORS.CFG line for lr-mame2015 is

      lr-mame2015 = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mame2015/mame2015_libretro.so --config /opt/retropie/configs/arcade/retroarch.cfg %ROM%"

      But I can't begin to guess how to alter that to run, say, a Bally Astrocade game, and just putting it in like that (with the last bit changed to astrocade/retroarch.cfg -cart %ROM%) results in a crash because it's trying to run an arcade game called "spacefrt" instead of the Astrocade one.

Required files are missing, the game cannot be run.

      (I tried installing lr-mess instead, but it gave me an incomprehensible error of needing a "gcc" of at least level 5.0, whatever the heck that means. Pretty sure it requires defeating at least one wizard.)

        MAME incorporated MESS in May 2015 (Mame version 0.162), while the mame2015-libretro is based around the early 2015 (0.160) MAME version, so there's no MESS support in that core.

        Having said that, the Libretro MAME cores in RetroPie don't necessarily include the MESS (i.e. non-arcade) parts. There are separate packages - lr-mess and lr-mess2016 including the MESS bits.

          @mitu Ah. Bummer. Cheers for letting me know. Sadly I can't install lr-mess for some reason and as far as I've ever been able to ascertain neither lr-mame2016 nor lr-mess2016 actually run anything.

              @rkoster Cheers, but as I said, unfortunately I'm unable to install lr-mess for reasons I don't understand.
