By 2003, the major arcade systems of the 1990s (CPS-1, CPS-2, Neo-Geo, Sega System 16) had been successfully and accurately dumped. MAME 0.78 captured these dumps at a moment of high accuracy but before the bloat of later systems (like CHD hard drives for LaserDisc games or System 22 3D games). The result: a lean, mean, fighting-game-and-run-and-gun machine.
If you are using the newer core, it is highly backward compatible with the standard 0.78 ROMset, but it also has its own specialized "Plus" ROMset to take full advantage of the fixes.
Version 0.78, released in late 2003, was a significant milestone in MAME's history. At the time of its release, it was considered a state-of-the-art emulator, capable of running thousands of arcade classics from the 80s and 90s. Its popularity was not just due to its capabilities but also because of its timing. It was the leading MAME version during the rise of early homebrew emulation scenes, notably on the original Xbox, which helped cement its status as a standard.
Technically, yes. Modern MAME (version 0.260+) is vastly superior in accuracy. It emulates obscure protection chips, bad sprite flickering, and even the exact timing of CRT monitors. mame 078 romset
For anyone wondering if their favorite arcade games are in the 0.78 romset, the short answer is: probably yes, if it's a 2D title from the 80s or early-to-mid 90s. A complete 0.78 romset is a time capsule, encompassing all the games MAME could emulate (with varying degrees of perfection) in 2003.
Audio files for older games that used discrete sound circuitry the software couldn't emulate at the time.

Games built on shared arcade hardware (like Neo-Geo games) require a BIOS file (e.g., neogeo.zip ) to be present in the same folder as the game ROMs. Do not delete or uncompress these BIOS files. Final Thoughts
Arcade games often have a "Parent" clone (usually the original or US release) and "Clone" ROMs (regional variants, bootlegs, or 2-player versions). ROMset Type How it Works

Use the 0.78 ROMset specifically with the MAME 2003 (or lr-mame2003 ) emulator core.
