Pi Model or other hardware: Ubuntu 18.04.1 x64 on Acer Aspire laptop
Power Supply used: n/a
RetroPie Version Used: 4.4.2
Built From: Retropie setup script
USB Devices connected: KB
Controller used: none
Error messages received: none visible when launching in ES. see below for other details.
Log found in /dev/shm/runcommand.log (if relevant): see below
Guide used: https://retropie.org.uk/docs/Debian/
File: /opt/retropie/libretrocores/lr-mame/mamearcade_libretro.so
Emulator: Retroarch (lr-mame)
Attachment of config files:
How to replicate the problem: Follow the guide above to build RP on Ubuntu. Install the lr-mame core from experimental. Copy rom and bios to appropriate locations. Try to launch ROM.

Core seems to compile OK (no failure) but it is unable to be loaded in RA. I tried loading manually also and it won't.

I'm rebuilding the laptop now with Ubuntu 16.04 x86 and will test again.

UPDATE:

I downloaded the latest mame_libretro.so file from the RA buildbot site and copied it to /opt/retropie/libretrocores/lr-mame/mamearcade_libretro.so

MAME 0.200 ROMs launch as expected.

Still an issue with the compiled core.
