078 Plus Romset [work] - Mame

When searching for or building a MAME 0.78 Plus set, you will encounter three primary formats:

Standard MAME 0.78 romsets were built for the original 2003 version of MAME. The "Plus" version is a curated evolution that takes that 2003 baseline and backports hundreds of improvements from newer versions of MAME (up to version 0.188 and beyond).

While 95% of the games are identical to the standard 0.78 set, the Plus version adds support for roughly 350 additional games and clones that were previously unplayable in the original 2003 core.
