Unlike other libretro MAME cores which remain fixed at one MAME version, MAME 2003-Plus is actively backporting more recent game drivers and features. MAME 2003-Plus is a new arcade emulator core which prioritizes 1) usability and frontend integration, 2) performance, and 3) compatibility across the range of libretro-supported platforms including mobile devices, single board computers, and consoles. In Summer 2018, RetroArch added MAME 2003-Plus to the arcade section of its Core Updater.
